matPutArrayAsGlobal
Put mxArrays into MAT-files
#include "mat.h" int matPutArrayAsGlobal(MATFile *mfp, const mxArray *mp);
mfpPointer to MAT-file information.
mp
This routine allows you to put an mxArray into a MAT-file. matPutArrayAsGlobal is similar to matPutArray, except the array is loaded by MATLAB into the global workspace and a reference to it is set in the local workspace. If you write to a MATLAB 4 format file, matPutArrayAsGlobal will not load it as global, and will act the same as matPutArray.
matPutArrayAsGlobal writes mxArray mp to the MAT-file mfp. If the mxArray does not exist in the MAT-file, it is appended to the end. If an mxArray with the same name already exists in the file, the existing mxArray is replaced with the new mxArray by rewriting the file. The size of the new mxArray can be different than the existing mxArray.
matPutArrayAsGlobal returns 0 if successful and nonzero if an error occurs. Use feof and ferror from the Standard C Library with matGetFp to determine status.
See matdemo.c in the eng_mat subdirectory of the examples directory for a sample program that illustrates how to use the MATLAB MAT-file routines in a C program.
