Boolean sparse writing (Scilab gateway)

How to add boolean sparse matrix in a list.

Calling Sequence

Input argument profile:

SciErr createBooleanSparseMatrixInList(void* _pvCtx, int _iVar, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos)

Named variable profile:

SciErr createBooleanSparseMatrixInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int _iRows, int _iCols, int _iNbItem, const int* _piNbItemRow, const int* _piColPos)

Arguments

_pvCtx: Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h.
_iVar: Position in the Scilab memory where you want to put the variable.
_pstName: Name of the variable for "named" functions.
_piParent: Address of the parent of the new item.
_iItemPos: Position of the new item in the list.
_iRows: Number of rows of the new variable.
_iCols: Number of columns of the new variable.
_iNbItem: Number of non zero itmes in the sparse.
_piNbItemRow: Number of item in each rows (size: _iRows).
_piColPos: Column position for each item (size: _iNbItem).
SciErr: Error structure where is stored errors messages history and first error number.

This help describes how to add boolean sparse matrix in a list.
