Boolean sparse reading (Scilab gateway)

How to read boolean sparse in a list.

Syntax

Input argument profile:

SciErr getBooleanSparseMatrixInList(void* _pvCtx, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbItem, int** _piNbItemRow, int** _piColPos)

Named variable profile:

SciErr readBooleanSparseMatrixInNamedList(void* _pvCtx, const char* _pstName, int* _piParent, int _iItemPos, int* _piRows, int* _piCols, int* _piNbItem, int* _piNbItemRow, int* _piColPos)

Arguments

_pvCtx

Scilab environment pointer, pass in "pvApiCtx" provided by api_scilab.h

_piParent

Address of the parent of the new item.

_pstName

Name of the variable for "named" functions.

_iItemPos

Position of the new item in the list.

_piRows

Return number of rows of the variable.

_piCols

Return number of columns of the variable.

_piNbItem

Return number of non zero value.

_piNbItemRow

Return number of item in each rows (size: _iRows).

_piColPos

Return column position for each item (size: _iNbItem).

SciErr

Error structure where is stored errors messages history and first error number.

Description

This help describes how to read boolean sparse in a list.
