title: Matrix Multiply method in C#
body: <p>I dont really understand the method Matrix.Multiply(Matrix m) in C#.</p>
  
  <p>Let say I have 2 matrices. 1 matrix is in world space and 1 matrix in local space, now I want to transform world space to local space or from local space to world space, what should I do with the Multiply method?</p>
  
  <pre><code>Matrix world = ....
  
  Matrix local = ...
  
  world.Multiply(local) 
  // It means world*local or local*world and it will transform world space to 
  // local or from local to world space?
  </code></pre>
  
  <p>Thank in advance.</p>
