## SIMatrix3.TransposeInPlace

### Description

Transposes this matrix in place: this = Transpose(this)

### C# Syntax

    SIMatrix3.TransposeInPlace();

### Scripting Syntax

    SIMatrix3.TransposeInPlace();

### Examples

#### 1. VBScript Example

    dim m1
    ' Create 3x3 matrix.
    set m1 = XSIMath.CreateMatrix3(1.0, 2.0, 3.0, 4.0, 5.0, 6.0, 7.0, 8.0, 9.0)
    m1.TransposeInPlace

#### 2. JScript Example

    var oRoot = Application.ActiveProject.ActiveScene.Root
    // Create two cubes, the first one is rotated and second
    // is the transpose in place of the first one
    var oCube = oRoot.AddGeometry("Cube","MeshSurface", "Cube")
    var oCube2 = oRoot.AddGeometry("Cube","MeshSurface", "Cube2")
    var oTrans = oCube.Kinematics.Local.Transform
    var oTrans2 = oCube2.Kinematics.Local.Transform
    var oMat3 = XSIMath.CreateMatrix3()
    oTrans2.GetRotationMatrix3 ( oMat3 );
    // Modify the matrix to scale and rotate around z
    oMat3.value(0,0) = 2 * Math.cos (45);
    oMat3.value(0,1) = -2 * Math.sin (45);
    oMat3.value(1,1) = 2 * Math.cos (45);
    oMat3.value(1,0) = 2 * Math.sin (45);
    oTrans.SetRotationFromMatrix3 ( oMat3 );
    oCube.Kinematics.Local.Transform = oTrans;
