TMtx.AddTensorProd Method

Summary

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

Class
TMtx

Declaration

Function AddTensorProd(Vec1, Vec2: TVec; ConjVec2: boolean = False): TMtx;

Description

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

Example 1

      var a,b: TMtx;
          v1,v2: TVec;
      begin
        CreateIt(a,b);
        CreateIt(v1,v2);
        try
          // Test non quadratic general matrix

          a.SetIt(2,2,False,[0,2,2,0]);
          v1.SetIt(false,[1,0]);
          v2.setIt(false,[0,1]);
          a.AddTensorProd(v1,v2,False);
          b.SetIt(False,[1,2,2,1]);
          if not a.Equal(b) then raise Exception.Create('Not same');
        finally
          FreeIt(a,b);
          FreeIt(v1,v2);
        end;
      end;
