matopen function in rapid accelerator in simulink

Hi,

I wish to use the functions of matopen and matGetVariable in the rapid accelerator mode of simulink. When I try this, I get an error because I need to include the mat.h file. This creates errors because of duplicate definitions of mxarray (mat.h includes matrix.h). I want to use this because I want to open mat in the mdlInitParameters function. I store all my parameters in a file because this way I can compare the models in an easy way and create them in an easy way (always using same file name,...).
