## SIVector3.MulByMatrix3

### Description

Right-multiplies the vector v by the matrix m and stores the result in this vector: this = v . m

### C# Syntax

    SIVector3.MulByMatrix3( SIVector3 in_pVector, SIMatrix3 in_pMatrix );

### Scripting Syntax

    SIVector3.MulByMatrix3( v, m );

### Parameters

Parameter | Type | Description
--- | --- | ---
v | SIVector3 | Operand vector
m | SIMatrix3 | Operand matrix

### Examples

#### VBScript Example

    dim v1, v2, m1

    ' Create 3D vectors.

    set v1 = XSIMath.CreateVector3

    set v2 = XSIMath.CreateVector3

    ' Create 3x3 matrix.

    set m1 = XSIMath.CreateMatrix3

    v1.Set 1.0, 2.0, 3.0

    m1.SetIdentity

    v2.MulByMatrix3 v1, m1
