Boolean sparse use case.

Description

This example shows how to get a boolean sparse variable and return it to Scilab.

Gateway Source

int booleanSparseExample(char *fname,unsigned long fname_len)
{
	SciErr sciErr;
	int* piAddr		= NULL;
	int iType		= 0;
	int iRet		= 0;

	CheckRhs(1,1);
	CheckLhs(0,1);

	sciErr = getVarAddressFromPosition(pvApiCtx, 1, &piAddr);
	if(sciErr.iErr)
	{
			printError(&sciErr, 0);
			return 0;
	}

	if(isBooleanSparseType(pvApiCtx, piAddr))
	{
		int iRows			= 0;
		int iCols			= 0;
		int iNbItem			= 0;
		int* piNbItemRow	= NULL;
		int* piColPos		= NULL;

		iRet = getAllocatedBooleanSparseMatrix(pvApiCtx, piAddr, &iRows, &iCols, &iNbItem, &piNbItemRow, &piColPos);
		if(iRet)
		{
			freeAllocatedBooleanSparse(piNbItemRow, piColPos);
			return iRet;

		sciErr = createBooleanSparseMatrix(pvApiCtx, Rhs + 1, iRows, iCols, iNbItem, piNbItemRow, piColPos);
		if(sciErr.iErr)
		{
			freeAllocatedBooleanSparse(piNbItemRow, piColPos);
			printError(&sciErr, 0);
			return sciErr.iErr;
		}

		freeAllocatedBooleanSparse(piNbItemRow, piColPos);
		LhsVar(1) = Rhs + 1;
	}
	return 0;
}
