Cannot Allocate An Array Of Size 0


A tag is like a keyword or category label associated with each thread. Is there a wage gap between smokers and non-smokers? From this C function, // simply call the C++ application function, above. //-------------------------------------------------------------- void mexFunction( int nlhs, mxArray *plhs[], int nrhs, const mxArray *prhs[] ) { temp65(nlhs, plhs, nrhs, prhs); } Sep 1, 2010 at 7:46pm UTC Looy (4) Thats basically it, its just a long list of Arrays (no main function).

Now you recommend using Matlab, if we are in a hurry. Variable Length Arrays, where the array size is determined at run-time, *are* part of the current C Standard, but they are *not* part of the C++ standard. Other times (and at other stages of debugging) it will close immediately, Windows will give me a (fatal) runtime error, or--my favorite--it won't return to the command line and won't let I am not a C Standard expert, so I don't know about the conformance of this, but IMO it is a serious flaw in the compiler that needs fixing even if

I began learning C++ and I finally managed to write my first MEX-file but when I'm trying to compile it I have (of course !) errors. Where in the analytic hierarchy is the theory of true set theory? The time now is 03:27 AM.

Why do I get this error? You cannot use 0 for array size and you MUST use a constant expression (as in, NOT a variable) for array size. this is the code: > > > > > > ... > > > > > // Variable declarations > > > > > int const nrOfFrames = (int)mxGetScalar(prhs[0]); ? // This way you can easily keep track of topics that you're interested in.

Jun 7 '14 at 1:14 This question has been asked before and already has an answer. http://electrictricycle.net/cannot-allocate/cannot-allocate-an-array-of-constant-size-0-visual-studio.html A better idea might be to use alloca, if the array size isn't going to be very large.

Your personal opinions about people who bring such facts to your attention are irrelevant.

I must be too tired or something. #include #include int main(void) { srand((unsigned)time(NULL)); int iRand_Num = rand()%20+1; int iArray[iRand_Num] = {0}; system("pause"); } C++ doesn't support VLA's.
