Mat_Open is not working while using matio in C++ about matio

[tbeu]

Please use Mat_Create or Mat_CreateVer instead of Mat_Open if the file does not exist.

Thanks for your quick answer. I changed the code like this:

mat = Mat_Create(filename, NULL);

I get the following error message: Process finished with exit code 139 (interrupted by signal 11: SIGSEGV). The data.mat file of 0 bytes is created.

Another question: do you have online documentation available?

[rbnvrw]

After debugging, I found the answer myself:
matvar = Mat_VarCreate("diffusion_trajectories", MAT_C_DOUBLE, MAT_T_DOUBLE, 3, dims, &trajectories->at(0), 0);

Thanks for your help!

Sure, up-to-date documentation is available from bitbucket.org.

Data type of dims should be size_t* (not unsigned long*). This likely is the reason for the segmentation violation (as also observed at https://sourceforge.net/p/matio/discussion/609377/thread/e7afc89e).
