TMtx::AddTensorProd Method

TMtx Class

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

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 TMtx::Rows property is set to Vec1. TMtx::Length and TMtx::Cols property is set to Vec2. TMtx::Length and TMtx::Complex property of the calling matrix is adjusted automatically.

Examples
#include "MtxVec.h"
#include "Units.MtxVec.h"

using namespace Dew;
using namespace Dew::Math;
using namespace Dew::Math::Units::MtxVec;

void Example()
{
    TMtx *a, *b;
    TVec *v1, *v2;

    CreateIt(a, b);
    CreateIt(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->Equal(b)) throw tException("Not same");
    FreeIt(a, b);
    FreeIt(v1, v2);
}
