title: Array multiplication and matrix inversion with VBA
body: <p>I am trying to do some calculations with arrays.</p>
  
  <p>e.g. I want to solve <code>Ax=y</code>, so I use the following code to do so, where A is a square matrix and y is a col. vector. In VBA, A is an array with two dimension and y is one with one dimension. However, this code does not work...</p>
  
  <pre><code>x = WorksheetFunction.MMult(WorksheetFunction.MInverse(A), y)
  </code></pre>
  
  <p>Where did I get wrong? Thanks!</p>
