Writing MAT files: Access violation writing location after 508 successful calls
It appears that you are running out of file handles, because you keep calling matOpen but then don't subsequently call matClose. Most systems impose an upper limit on the number of concurrently open files - it would appear that on your system this limit is 512 - there are already...
How to access the “Value” in a .mat file without knowing the name?
Use M=load(matfile);, then you get a struct with all variables in the matfile. Use f=fieldnames(M) to get a list of all variables in the struct and M.(f{1}) to access the first variable (assuming you have only 1)
How to append in .mat file row or columnwise cellmatrix
You can use matfile with cells as long as you are not trying to index into the actual cells. Remember that cells are still arrays, so you can access each cell using array indexing. For example: >> x = {'this', 'is', 'an', 'example'}; >> x{4} ans = example >> x(4)...
Errors in linking fortran code that imports a MAT-file [duplicate]

As pointed out by Alexander Vogt, the compiler requires -cpp option for the pre-processor to recognize the header file and not to treat it as illegal. Linking requires finitrf.h which is usually located in the <matlabroot>/extern/include and the essential libraries are present in <matlabroot>/bin/<arch>/. But just specifying this does not...
