TMtx.Determinant Methods

Summary

Determinant of squared matrix.

Class
TMtx

Declaration

Procedure Determinant(out Result: TCplx; MtxType: TMtxType = mtGeneral);

Description

Calculates the determinant of squared complex matrix and returns the result in Result complex variable. An exception is raised if the calling matrix Complex property is false.

Declaration

Function Determinant(MtxType: TMtxType = mtGeneral): TSample;

Description

Calculate the determinant of squared real matrix. An exception is raised if the calling matrix Complex property is true.

Example 1

      var A: TMtx;
          b: TSample;
      begin
        CreateIt(A);
        try
          A.SetIt(2,2,false,[1,2,
                            2,4]);  // 2x2, not complex matrix
          b := A.Determinant; // 4 + 4 = 9
        finally
          FreeIt(A);
        end;
      end;
