IMath.MInverse

Syntax

MInverse(Data: Array): Array;

Parameters

Data. Array of real numbers.

Description

The MInverse method returns a reverse matrix for the specified array.

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
    MInv, matr: Array Of Double;
    i, j: Integer;
Begin
    matr := New Double[3, 3];
    matr[0, 0] := 1; matr[0, 1] := 9; matr[0, 2] := 9;
    matr[1, 0] := 2; matr[1, 1] := 15; matr[1, 2] := 0;
    matr[2, 0] := 8; matr[2, 1] := 1; matr[2, 2] := 13;
    MInv := Math.MInverse(matr);
    If math.Status = 0 Then
        For i := 0 To MInv.GetUpperBound(1) Do
            For j := 0 To MInv.GetUpperBound(2) Do
                Debug.Write(MInv[i, j].ToString + " ");
            End For;
            Debug.WriteLine("");
        End For;
        Else
        Debug.WriteLine("Error " + Math.Status.ToString + ": " + Math.ErrorMsg);
    End If;
End Sub UserProc;

After executing the example the console window displays the reverse matrix.
