Hey,
I have a problem that mex files generated by MatLab Coder only supports 32bit indexing, which is the reason my program gets an error when the input of the bottleneck mex function exceeds an input boolean matrix which has more than 2^31 elements.
I know that mex-files support 64bit indexing when they are hand written, but since I am not comfortable with c or c++, I wonder if there is a way, and if so how, to manually correct this at the end of the coder when it shows me the code it generated?
I read that i shoukld have to replace the 'int32_T' by 'size_t' but thats not all, I would also need to replace the the constructors 'coder::array<T, 1U>' with C MEX API... and thats the point where my knowledge ends and I would need some help about what to do exactly and how to do it.
May be someone coukld help me with that.
Best regards and many thanks in advance

So you will need to manually change the codein C/C++ files.
You can refer to the guide to enable support for 64-bit indexing in MEX files using compatibleArrayDims flag in mex command.
You can use these additional instructions to upgrade MEX files to use 64-Bit API.

I first tried to recompile the coder code with matlab again, just to be sure that it will work. Untill this would not work I should not be concerned about changing the code because I cant compile it.
So I tried it but i got tonnes of error messages which I did understand:

collect2.exe: error: ld returned 1 exit status
I dont get why emlrtAlias and many other cand be found, the folder extern/include where this header is, is named in the path at the top. I can even copy the emlrt.h into the directory where the cpp's are and it still says the same error.
exist('...\emlrt.h', 'file')=2, so the file is there...
Whats the problem?
