IMatrixModel.Dereference

Syntax

Dereference(FixInfo: IMatrixModelFixInfo): IMatrixModel;

Parameters

FixInfo. Information on fixed dimensions, according to which the matrix is rebuilt.

Description

The Dereference method rebuilds a matrix taking into account fixed dimension elements.

Comments

After executing the method a matrix reduced by the number of fixed dimensions is returned.

Example

Sub Main;
Var
    M: Matrix[3];
    M1, M2: Matrix[2];
    Mm: IMatrixModel;
    x, y, z: Integer;
    Fix: IMatrixModelFixInfo;
Begin
    Debug.WriteLine("Source matrix");
    For x := 0 To 2 Do
        For y := 0 To 2 Do
            For z := 0 To 2 Do
                M[x, y, z] := Math.RandBetweenI(0, 9);
                Debug.Write(M[x, y, z] + " ");
            End For;
            Debug.WriteLine("");
        End For;
        Debug.WriteLine("");
    End For;
    Mm := M As IMatrixModel;
    Fix := Mm.CreateFixInfo;
    Fix.Item(0) := 0;
    M1 := Mm.Dereference(Fix);
    Fix.Clear;
    Fix.Item(0) := 1;
    M2 := Mm.Dereference(Fix);
    Debug.WriteLine("----------------");
    For y := 0 To 2 Do
        For z := 0 To 2 Do
        Debug.Write(M1[y, z] + " ");
        End For;
        Debug.WriteLine("");
    End For;
    Debug.WriteLine("");
    For y := 0 To 2 Do
        For z := 0 To 2 Do
            Debug.Write(M2[y, z] + " ");
        End For;
        Debug.WriteLine("");
    End For;
End Sub Main;

After executing the example a 3x3x3 matrix of random numbers will be generated. Two more matrices will be obtained on the basis of this matrix, by fixing the source one by the X dimension. The M1 matrix is obtained by fixing the source matrix by the first element of the X dimension, M2 is by fixing by the second element of the X dimension. All the dimensions of the source matrix and M1 and M2 matrices will be displayed.
