Matrix::AddTensorProd Method

Matrix Struct

TMtx *AddTensorProd(TVec *Vec1, TVec *Vec2, bool ConjVec2 = false) const;

Calculates the tensor product of two vectors and adds the result to calling matrix.

#NameTypeDescription
1Vec1TVec *
2Vec2TVec *
3ConjVec2 = falsebool
Remarks:

Calculates the tensor product of Vec1 and Vec2 vectors and adds the result to the calling matrix by using the following formula:

Y=Vec1 X Vec2 + Y.

If the ConjVec2 parameter is true, then the result will be tensor product of Vec1 and conjugated Vec2. The Matrix::Rows property is set to Vec1.Matrix::Length and Matrix::Cols property is set to Vec2.Matrix::Length. The Matrix::Complex property of the calling matrix is adjusted automatically.

Examples
#include "MtxExpr.h"

using namespace Dew;
using namespace Dew::Math;

void Example()
{
    Matrix a, b;
    Vector v1, v2;

    // Test non quadratic general matrix

    a.SetIt(2, 2, false, DewArray<double>{0, 2, 2, 0});
    v1.SetIt(false, DewArray<double>{1, 0});
    v2.SetIt(false, DewArray<double>{0, 1});
    a.AddTensorProd(v1, v2, false);
    b.SetIt(2, 2, false, DewArray<double>{0, 3, 2, 0});
    if (!(a == b)) throw tException("Not same");
}
