• C pointer array scope and function calls

  - by juvenis

  I have this situation: { float foo[10]; for (int i = 0; i < 10; i++) { foo[i] = 1.0f; } object.function1(foo); // stores the float pointer to a const void* member of object } object.function2(); // uses the stored void pointer Are the contents of the float pointer unknown in the second function call? It seems that I get weird results when I run my program. But if I declare the float foo[10] to be const and initialize it in the declaration, I get correct results. Why is this happening?

• Converting Single dimensional vector or array to two dimension in Matlab

  - by pac

  Well I do not know if I used the exact term. I tried to find an answer on the net. Here is what i need: I have a vector a = 1 4 7 2 5 8 3 6 9 If I do a(4) the value is 4. So it is reading first column top to buttom then continuing to next .... I don't know why. However, What I need is to call it using two indices. As row and column: a(3,2)= 4 or even better if i can call it in the following way: a{3}(2)=4 What is this process really called (want to learn) and how to perform in matlab. I thought of a loop. Is there a built in function Thanks a lot Check this: a = 18 18 16 18 18 18 16 0 0 0 16 16 18 0 18 16 0 18 18 16 18 0 18 18 0 16 0 0 0 18 18 0 18 18 16 0 16 0 18 18 >> a(4) ans = 18 >> a(5) ans = 18 >> a(10) ans = 18 I tried reshape. it is reshaping not converting into 2 indeces

• Memory leaks while using array of double

  - by Gacek

  I have a part of code that operates on large arrays of double (containing about 6000 elements at least) and executes several hundred times (usually 800) . When I use standard loop, like that: double[] singleRow = new double[6000]; int maxI = 800; for(int i=0; i<maxI; i++) { singleRow = someObject.producesOutput(); //... // do something with singleRow // ... } The memory usage rises for about 40MB (from 40MB at the beggining of the loop, to the 80MB at the end). When I force to use the garbage collector to execute at every iteration, the memory usage stays at the level of 40MB (the rise is unsignificant). double[] singleRow = new double[6000]; int maxI = 800; for(int i=0; i<maxI; i++) { singleRow = someObject.producesOutput(); //... // do something with singleRow // ... GC.Collect() } But the execution time is 3 times longer! (it is crucial) How can I force the C# to use the same area of memory instead of allocating new ones? Note: I have the access to the code of someObject class, so if it would be needed, I can change it.

• Counting array in API JSON Response

  I'm trying to do a simple count of how many refunds are in my Stripe Response but count() isn't working and I don't really know any other way of achieving this. Could anyone point me in the right direction? $retrieve_event = Stripe_Event::retrieve("evt_00000000000000"); $event_json_id = json_decode($retrieve_event); $refund_array = $event_json_id->{'data'}->{'object'}->{'refunds'}; die(count($refund_array)); This is the response of $retrieve_event { "created": 1326853478, "livemode": false, "id": "evt_00000000000000", "type": "charge.refunded", "object": "event", "request": null, "data": { "object": { "id": "ch_00000000000000", "object": "charge", "created": 1402433517, "livemode": false, "paid": true, "amount": 1000, "currency": "usd", "refunded": true, "card": { "id": "card_00000000000000", "object": "card", "last4": "0028", "type": "Visa", "exp_month": 8, "exp_year": 2015, "fingerprint": "a5KWlTcrmCYk5DIYa", "country": "US", "name": "First Last", "address_line1": "null", "address_line2": null, "address_city": "null", "address_state": "null", "address_zip": "null", "address_country": "US", "cvc_check": null, "address_line1_check": "fail", "address_zip_check": "pass", "customer": "cus_00000000000000" }, "captured": true, "refunds": [ { "id": "re_104CKt4uGeYuVLAahMwLA2TK", "amount": 100, "currency": "usd", "created": 1402433533, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaSNZCR867", "metadata": {} }, { "id": "re_104CKt4uGeYuVLAaDIMHoIos", "amount": 200, "currency": "usd", "created": 1402433539, "object": "refund", "charge": "ch_104CKt4uGeYuVLAazSyPqqLV", "balance_transaction": "txn_104CKt4uGeYuVLAaqSwkNKPO", "metadata": {} }, { "id": "re_4CL6n1r91dY5ME", "amount": 700, "currency": "usd", "created": 1402434306, "object": "refund", "charge": "ch_4CL6FNWhGzVuAV", "balance_transaction": "txn_4CL6qa4vwlVaDJ" } ], "balance_transaction": "txn_00000000000000", "failure_message": null, "failure_code": null, "amount_refunded": 1000, "customer": "cus_00000000000000", "invoice": null, "description": "this is a description", "dispute": null, "metadata": {}, "statement_description": "this is a description", "fee": 0 } } }

• Serialize checkbox array, also get checkboxes with off-value

  - by guzh

  Hi, I was wondering if this is possible. The serialize-string will be inserted in a mySQL-database, so it would be fine if all checkboxes would be inserted and not only the ones that is ticked(on). it's possible to make on column in the database for each of the checkboxes, and use this if/else-statement: if(isset($_GET['checkbox'])) { // It's checked! } else { // not checked! } but its a bit unappropriate...

• Java webservice does not return all struct array

  - by Aykut

  Hi I wrote a webservice which runs correctly. In the webservice, there is a class which contains other classes' arrays and the webservice returns this class's instance. for example public class cls1 implements Serializable{ cls2[] cls2Arr; cls3[] cls3Arr; } I fill this arrays (cls2Arr and cls3Arr) correctly in service side. When I read this arrays from client, I see only last item of arrays. I checked on the service side before the webservice returns, and the cls1 instance and everything else looked good. What can be a reason ? Thx

• Copying a 2D non-space array to another

  - by Jay

  I'm a total programming newb who started learning java programming this sem at uni. I'm up to a step where i need to copy some elements from one method to another. This program i'm creating is called an L_Game. The question I'm stuck is: the project(Slide other) method should take another slide as a parameter, and copy each non-space cell from this slide into the other slide (i.e. like a projector projecting slides onto a screen. I previously made a constructor with the parameter cells in it and believe i copied it to the project(Slide other) method. But i'm not sure what to do to copy each "non-space cell" With the "for" method or the "if" method? If my question isn't typed correctly or have information missing, please let me know. Any help will be appreciated. (I obviously have no idea with what i'm doing...)

• How can I get a iterable resultset from the database using pdo, instead of a large array?

  - by Tchalvak

  I'm using PDO inside a database abstraction library function query. I'm using fetchAll(), which if you have a lot of results, can get memory intensive, so I want to provide an argument to toggle between a fetchAll associative array and a pdo result set that can be iterated over with foreach and requires less memory (somehow). I remember hearing about this, and I searched the PDO docs, but I couldn't find any useful way to do that. Does anyone know how to get an iterable resultset back from PDO instead of just a flat array? And am I right that using an iterable resultset will be easier on memory? I'm using Postgresql, if it matters in this case. . . . The current query function is as follows, just for clarity. /** * Running bound queries on the database. * * Use: query('select all from players limit :count', array('count'=>10)); * Or: query('select all from players limit :count', array('count'=>array(10, PDO::PARAM_INT))); **/ function query($sql_query, $bindings=array()){ DatabaseConnection::getInstance(); $statement = DatabaseConnection::$pdo->prepare($sql_query); foreach($bindings as $binding => $value){ if(is_array($value)){ $statement->bindParam($binding, $value[0], $value[1]); } else { $statement->bindValue($binding, $value); } } $statement->execute(); // TODO: Return an iterable resultset here, and allow switching between array and iterable resultset. return $statement->fetchAll(PDO::FETCH_ASSOC); }

• Program crash for array copy with ifort

  - by Stefano Borini

  This program crashes with Illegal instruction: 4 on MacOSX Lion and ifort (IFORT) 12.1.0 20111011 program foo real, pointer :: a(:,:), b(:,:) allocate(a(5400, 5400)) allocate(b(5400, 3600)) a=1.0 b(:, 1:3600) = a(:, 1:3600) print *, a print *, b deallocate(a) deallocate(b) end program The same program works with gfortran. I don't see any problem. Any ideas ? Unrolling the copy and performing the explicit loop over the columns works in both compilers. Note that with allocatable instead of pointer I have no problems. The behavior is the same if the statement is either inside a module or not. I confirm the same behavior on Linux using ifort (IFORT) 12.1.3 20120130.

• How to pass checkbox array to Java from jsp

  - by eddy

  Hi, I'd like to know if there's any way to send data to the server for the selected rows using the checkboxes I've put on those rows? I mean , how can I send only the data of those selected rows to the server? Here's the html code I use: <table> <thead> <tr class="tableheader"> <td width="10%"></td> <td width="30%">Vehicle</td> <td width="40%">Driver</td> <td width="10%">Mileage</td> </tr> </thead> <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectedItems" value="c:out value="${item.numberPlate}"/>"/> </td> <td align="left"><c:out value="${item.numberPlate}"/></td> <td align="left"><c:out value="${item.driver.fullName}" /></td> <td align="left"><input type="text" name="mileage" value="" /></td> </tr> </c:forEach> </tbody> </table> I really hope you can give some guidance on this. Thanks in beforehand.

• Placing error message for a checkbox array

  - by eddy

  Hello all. I am using the Validation Plugin for jQuery and it works wonders. Except when I have a group of checkboxes...the error messages will display right after the first checkbox...like so: <tbody> <c:forEach items="${list}" var="item"> <tr> <td align="center"> <input type="checkbox" name="selectItems" value="<c:out value="${item.numberPlate}"/>" /> </td> <!--some other columns--> </tr> </c:forEach> </tbody> I found that I can use a wrapper for these checkboxes ,then place the error message there, but I have no idea how to do it since I'm creating the rows dynamically. Hope you can help me out.

• Divide numpy array

  - by BandGap

  Hi all I have some data represented in a 1300x1341 matrix. I would like to split this matrix in several pieces (e.g. 9) so that I can loop over and process them. The data needs to stay ordered in the sense that x[0,1] stays below (or above if you like) x[0,0] and besides x[1,1]. Just like if you had imaged the data, you could draw 2 vertical and 2 horizontal lines over the image to illustrate the 9 parts. If I use numpys reshape (eg. matrix.reshape(9,260,745) or any other combination of 9,260,745) it doesn't yield the required structure since the above mentioned ordering is lost... Did I misunderstand the reshape method or can it be done this way? What other pythonic/numpy way is there to do this?

• Android onClickListener options and help on creating a non-static array adapter

  - by CoderInTraining

  I am trying to make an application that gets data dynamically and displays it in a listView. Here is my code that I have with static data. There are a couple of things I want to try and do and can't figure out how. MainActivity.java package text.example.project; import java.util.ArrayList; import java.util.Arrays; import java.util.Collections; import android.app.ListActivity; import android.os.Bundle; import android.view.View; import android.widget.AdapterView; import android.widget.AdapterView.OnItemClickListener; import android.widget.ArrayAdapter; import android.widget.ListView; import android.widget.TextView; import android.widget.Toast; public class MainActivity extends ListActivity { //declarations private boolean isItem; private ArrayAdapter<String> item1Adapter; private ArrayAdapter<String> item2Adapter; private ArrayAdapter<String> item3Adapter; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Collections.sort(ITEM1); Collections.sort(ITEM2); Collections.sort(ITEM3); item1Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM1); item2Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM2); item3Adapter = new ArrayAdapter<String>(this, R.layout.list_item, ITEM3); setListAdapter(item1Adapter); isItem = true; ListView lv = getListView(); lv.setTextFilterEnabled(true); lv.setOnItemClickListener(new OnItemClickListener() { @Override public void onItemClick(AdapterView<?> parent, View view, int position, long id) { // When clicked, show a toast with the TextView text if (isItem) { //ITEM1.add("another\n\t" + Calendar.getInstance().getTime()); Collections.sort(ITEM1); item2Adapter.notifyDataSetChanged(); setListAdapter(item2Adapter); isItem = false; } else { item1Adapter.notifyDataSetChanged(); setListAdapter(item1Adapter); isItem = true; } Toast.makeText(getApplicationContext(), ((TextView) view).getText(), Toast.LENGTH_SHORT).show(); } }); } // need to turn dynamic static ArrayList<String> ITEM1 = new ArrayList<String> (Arrays.asList( "ITEM1-1", "ITEM1-2" )); static ArrayList<String> ITEM2 = new ArrayList<String> (Arrays.asList( "ITEM2-1", "ITEM2-2" )); static ArrayList<String> ITEM3 = new ArrayList<String> (Arrays.asList("ITEM3-1", "ITEM3-2")); } list_item.xml <?xml version="1.0" encoding="utf-8"?> <TextView xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="10dp" android:textSize="16sp" > </TextView> What I want to do is first pull from a dynamic source. I need to do what is almost exactly like this tutorial... http://androiddevelopement.blogspot.in/2011/06/android-xml-parsing-tutorial-using.html ... however, I can't get the tutorial to work... I also would like to know how I can make the list item clicks so that if I click on "ITEM1-1" it goes to the menu "ITEM2-1" and "ITEM2-2". and if "ITEM1-2" is clicked, then it goes to the menu with "ITEM3-1" and "ITEM3-2"... I am totally a noob at this whole android development thing. So any suggestions would be great!

• add uchar values in ushort array with sse2 or sse3

  - by pompolus

  i have an unsigned short dst[16][16] matrix and a larger unsigned char src[m][n] matrix. Now i have to access in the src matrix and add a 16x16 submatrix to dst, using sse2 or ss3. In a my older implementation, I was sure that my summed values ??were never greater than 256, so i could do this: for (int row = 0; row < 16; ++row) { __m128i subMat = _mm_lddqu_si128(reinterpret_cast<const __m128i*>(src)); dst[row] = _mm_add_epi8(dst[row], subMat); src += W; // Step to next row i need to add } where W is an offset to reach the desired rows. This code works, but now my values in src are larger and summed could be greater than 256, so i need to store them as ushort. i've tried this: for (int row = 0; row < 16; ++row) { __m128i subMat = _mm_lddqu_si128(reinterpret_cast<const __m128i*>(src)); dst[row] = _mm_add_epi16(dst[row], subMat); src += W; // Step to next row i need to add } but it doesn't work. I'm not so good with sse, so any help will be appreciated.
