getHypermatOfDouble

Get a hypermatrix of double variable.

Syntax

SciErr getHypermatOfDouble(void* _pvCtx, int* _piAddress, int **_dims, int *_ndims, double* _pdblReal)

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.

_pdblReal

Double values.

Return value

A SciErr struct, the field iErr would contain the error number (0 if no error).
