IMath.MDeterm

Syntax

MDeterm(Data: Array): Double;

Parameters

Values. Array of real numbers.

Description

The MDeterm method returns the determinant of the specified matrix.

Comments

The matrix must be square.

If an input array contains gaps, the function returns error.

Example

To execute the example, add a link to the MathFin system assembly.

Sub UserProc;
Var
    matr: Array Of Double;
    r: Double;
Begin
    matr := New Double[4, 4];
    matr[0, 0] := 1; matr[0, 1] := 3; matr[0, 2] := 8; matr[0, 3] := 5;
    matr[1, 0] := 1; matr[1, 1] := 3; matr[1, 2] := 6; matr[1, 3] := 1;
    matr[2, 0] := 1; matr[2, 1] := 1; matr[2, 2] := 1; matr[2, 2] := 0;
    matr[3, 0] := 7; matr[3, 1] := 3; matr[3, 2] := 10; matr[3, 3] := 2;
    r := Math.MDeterm(matr);
    Debug.WriteLine(r);
End Sub UserProc;

After executing the example the console window displays the result of the product equal to 2250.
