Calling Sequence
SciErr getHypermatOfInt8(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, char* _pcData)
SciErr getHypermatOfUnsignedInt8(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, unsigned char* _pucData)
SciErr getHypermatOfInt16(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, short* _psData)
SciErr getHypermatOfUnsignedInt16(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, unsigned short* _pusData)
SciErr getHypermatOfInt32(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, int* _piData)
SciErr getHypermatOfUnsignedInt32(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, unsigned int* _puiData)
Arguments
- _pvCtx
Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.
- _piAddress
Address of the Scilab variable.
- _dims
the hypermatrix dimensions.
- _ndims
the number of dimensions.
- _p*Data
the data.
Return value
A SciErr struct, the field iErr would contain the error number (0 if no error).
