Question

When I try to use MATLAB mex command to compile a c file, I met the following error

error: unknown type name ‘mxArray’

The error code is here

const char *model_to_matlab_structure(mxArray *plhs[], int num_of_feature, struct svm_model *model);
struct svm_model *matlab_matrix_to_model(const mxArray *matlab_struct, const char **error_message);

I don’t understand why MATLAB doesn’t recognize the mxArray type. How could I resolve this? Thanks!

Thanks. It turns out that I forgot

#include "mex.h"
