• C++: Pass array created in the function call line

  - by Jarx

  How can I achieve a result like somebody would expect it according to the following code example: // assuming: void myFunction( int* arr ); myFunction( [ 123, 456, 789 ] ); // as syntactical sugar for... int values[] = { 123, 456, 789 }; myFunction( values ); The syntax I thought would work spit out a compile error. How can I define an argument array directly in the line where the function is called?

• Help me understand FFT function (Matlab)

  - by estourodepilha.com

  1) Besides the negative frequencies, which is the minimum frequency provided by the FFT function? Is it zero? 2) If it is zero how do we plot zero on a logarithmic scale? 3) The result is always symmetrical? Or it just appears to be symmetrical? 4) If I use abs(fft(y)) to compare 2 signals, may I lose some accuracy?

• How to use an overloaded function as an argument of function template?

  - by hpsmouse

  Hello, I think everyone has experience working with a code like the following: void fun(Type1&); void fun(Type2&); vector<Type1> vec; for_each(vec.begin(), vec.end(), fun); Of course that won't compile, because it's not clear which function to be passed. And what's your commonly-used solution to the problem?

However, when I try to setup an Index on that column, I see a size of nvarchar(4000). Why is that and will that cause a problem if I continue to setup my index?

• run a function when a user clicks on any list element

  - by sova

  This is probably a very common question, but I was unable to find an answer myself; All my list elements call the function setQuery like this onClick="admin_stats.setQuery(this);" rather than [hardcode] add this to every list element, is there a way to simply have it run when a list element is clicked? I'm not very familiar with jQuery Live or binding/unbinding, but I think they would play a role here? Before I reinvent a rather square-looking wheel I thought I might ask =)
