title: Creating a correlation matrix via Excel VBA
body: <p>What would be the best way to create a correlation matrix via Excel VBA?  My data has 45 columns (which may eventually change) and 12000 rows (which can change as well).  I was going to just use the <code>correl</code> function on the sheet but like I said, my columns and rows may change with time.</p>
  
  <p>Any help will be greatly appreciated!</p>
