#include "mat.h" MATFile *matOpen(const char *filename, const char *mode);
filename
mfp
Pointer to MAT-file information.
mode
This routine allows you to open MAT-files for reading and writing.
matOpen
opens the named file and returns a file handle, or NULL
if the open fails. Legal values for mode
are
r | Opens file for reading only; determines the current version of the MAT-file by inspecting the files and preserves the current version. |
u | Opens file for update, both reading and writing; determines the current version of the MAT-file by inspecting the files and preserves the current version. |
w | Opens file for writing only; deletes previous contents, if any. |
w4 | Creates a MATLAB 4 MAT-file, rather than the default MATLAB 5 MAT-file. |
