  • Grayscale in matlab

    - by ruthenium
    I'm trying to convert a 2D array to grayscale but using mat2gray doesn't do anything and imshow() appears to create a binary image that when I graph I cannot rotate it, e.g. the original array is 2d but maps in 3d. So, what is the best way to take a grayscale of 2d array in Matlab so if you have A=rand(5,10) or something and want to take a grayscale of that, what is the best way?

  • matlab write image into eps file

    - by Tim
    In MATLAB, how do you write a matrix into an image of eps format? It seems imwrite does not support eps? convert is not working on the Linux server I am using $ convert exploss_stumps.jpg exploss_stumps.eps convert: missing an image filename `exploss_stumps.eps' @ convert.c/ConvertImageCommand/2838 Any idea why?

  • Best way to organize MATLAB classes?

    - by jjkparker
    MATLAB has two ways of organizing classes: @-directories: @ClassName\ ClassName.m Method1.m Method2.m Single files: ClassName.m: classdef ClassName methods % all methods included here end end The first style existed before the new classdef syntax, but seems to be a more structured way of doing things. The second style (everything in a single file) is new. Which method do you use, and why?

  • Basic Matlab question

    - by sylvester
    I know this is really basic, but I am new to matlab. After opening a .fig file, how do you actually work with the data in the command line? All I see is the picture. Im not sure how to actually get the data.

  • GCD function in matlab

    - by SalemFayad
    hi, i am looking for a way to implement the "gcd" function used in matlab in another language but i really cant understand the way it functions. it says in http://www.mathworks.com/access/helpdesk/help/techdoc/ref/gcd.html that: "[G,C,D] = gcd(A,B) returns both the greatest common divisor array G, and the arrays C and D, which satisfy the equation: A(i).*C(i) + B(i).*D(i) = G(i)." but it says nothing about how it calculates C and D. i would be grateful if someone has a clearer idea about this subject! thanks:)

  • Problem with y-axis in Matlab Diagram

    - by Claus
    Hi, I am drawing a simple bar diagram in Matlab. The problem is, that the value at x = 0 lets the y-axis disappear partially. Is there a way to bring the y-axis to the front instead of hiding between the y-value for x=0? Is there any option I can make sure the y-axis is always in the front? Many thanks, Claus

  • MATLAB image processing HELP!

    - by beho86
    Hello, I am trying to find the area of some regions on an image. http://img821.imageshack.us/img821/7541/cell1.jpg For example, I want find the area of the dark-large region on the upper left side. and I want to find the area of any of the closed geometry from the image. How can I do that in matlab. I looked online and I tried regionprops(), but it didn't identify the different regions.

  • Need a explanation for the matlab code snippet

    - by Mask
    %# load a grayscale image img = imread('coins.png'); %# display the image figure imshow(img,[]); %# false-color colormap('hot') The above code is from here: http://stackoverflow.com/questions/2592755/infrared-image-processing-in-matlab/2592793#2592793 But I don't understand how figure(What's the difference with/without it?) and colormap(How does it affect the already shown img?) work?

  • Plotting in Matlab

    - by papaduke
    How do you plot two figures at the same time in Matlab? Every time I use surf() it plots over the old one. Also, how do you save the images so you can export them to MS word or powerpoint or something?

  • MATLAB: Drawing a line over a black and white image

    - by Richard
    This is quite possibly an extremely retarded question, but what is the best way to draw a line over a black and white (binary) image in MATLAB, provided the start and end coordinates are known? Please note, I am not trying to add an annotation line, I would like the line to become part of the image.

  • implementation of interp1 function of MATLAB in J2ME

    - by Jeeka
    Hi, i am looking to implement the interp1, 1-D data interpolation (table lookup), function available in MATLAB in J2ME or JAVA. here is the link http://www.mathworks.com/access/helpdesk/help/techdoc/ref/interp1.html Is there any library available in J2ME or JAVA which has already implemented the same function ? If not can anybody help me in implementing interp1 function in J2ME or JAVA ?

  • MATLAB: Reading floating point numbers and strings from a file

    - by xsound
    I am using the following functions for writing and reading 4098 floating point numbers in MATLAB: Writing: fid = fopen(completepath, 'w'); fprintf(fid, '%1.30f\r\n', y) Reading: data = textread(completepath, '%f', 4098); where y contains 4098 numbers. I now want to write and read 3 strings at the end of this data. How do I read two different datatypes? Please help me. Thanks in advance.

  • How to override the default text in MATLAB

    - by Richie Cotton
    In MATLAB, when you click File - New - Function M-File, you get a file with the following contents: function [ output_args ] = Untitled( input_args ) %UNTITLED Summary of this function goes here % Detailed explanation goes here end Is it possible to override this behaviour, and specify your own text? (The motivation is that I'm trying to persuade my colleagues to document their m-files more thoroughly, and having default text for them to fill in might encourage them.)

  • Changing scaling of MATLAB Figure

    - by Phil
    I have a figure that displays 20,000 points on the x-axis. So it labels the x-axis from 0 ... 20,000. However, now I would like to scale it from 0 to 50. But when I try to do this in the plot window it just shows me the first 50 points, instead of changing the scale. Is there any straightforward way to do that in MATLAB?

  • Calculating the maximum distance between elements of vector in Matlab

    - by lhahne
    Lets assume that we have a vector like x = -1:0.05:1; ids = randperm(length(x)); x = x(ids(1:20)); I would like to calculate the maximum distance between the elements of x in some idiomatic way. It would be easy to just iterate over all possible combinations of x's elements but I feel like there could be a way to do it with Matlab's built-in functions in some crazy but idiomatic way. Any ideas?

  • Is there a substitute for blockproc in Matlab?

    - by SetchSen
    I've been using blockproc for processing images blockwise. Unfortunately, blockproc is part of the Image Processing Toolbox, which I don't have on my personal computer. Is there a combination of functions in base Matlab that can substitute for blockproc? My initial guess was to use im2col to transform each block into columns, and then arrayfun to process each column. Then I realized that im2col is also a part of the Image Processing Toolbox, so that doesn't solve my problem.
