Summary

Matrix array multiplication.

Class
TMtx

Declaration

Function MulElem(MTx1, Mtx2: TMtx): TMtx;

Description

Multiplies elements in Mtx1 matrix with the elements in Mtx2 matrix (array multiplication) and stores the results in calling matrix. The Rows, Cols and Complex properties of calling matrix are set implicitly to match those of Mtx1 and Mtx2 matrices. Mtx1 and Mtx2 Rows, Cols, and Complex properties must be the same, otherwise an excetion is raised. raised.

          A.SetIt(2,2,False,[1,2,
                             2,4]);
          B.SetIt(2,2,False,[1,2,
                             2,4]);
          C.MulElem(A,B);
          // C becomes:
          // [1, 4,
          //  4,16]
        finally
          FreeIt(A,B,C);
