TSparseMtx::MulLeft Method

Overload List

#	Signature	Description
1	void MulLeft(TMtx X, TMtx Y);	Multiply the sparse matrix from left.
2	void MulLeft(TVec X, TVec Y);	Multiply sparse matrix from left with vector X and place the result in vector Y.

Overload 1: void MulLeft(TMtx X, TMtx Y);

Multiply the sparse matrix from left.

#	Name	Type	Description
1	X	TMtx *
2	Y	TMtx *

Remarks:

Multiply calling sparse matrix from left with dense matrix X and place the result in dense matrix Y.

Examples

#include "MtxExpr.h"
#include "sparse.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Matrix a(3, 2);
    Matrix b(2, 3);
    TSparseMtx* aSparse = new TSparseMtx();
    Matrix s = {{1, 0, 2}, {0, 3, 0}};
    aSparse->DenseToSparse(s);
    aSparse->MulLeft(a, b); // result is stored in b
    delete aSparse;
}
