## 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

    NewScene (null, false);

    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;

    var vbArr = new VBArray( oMat3.Get2() );

    var array = vbArr.toArray();

    Application.LogMessage( "SIMatrix3 before transpose" +

    "m20:" + array[6] + " m21:" + array[7] + " m22:" + array[8] );

    oMat3.TransposeInPlace()

    oTrans2.SetRotationFromMatrix3 ( oMat3 );

    var vbArr = new VBArray( oMat3.Get2() );

    var array = vbArr.toArray();
