title: How to divide one matrix by another in Stata
body: <p>I have created two matrices with the following commands:  </p>
  
  <pre><code>tab year region if x==1, matcell(cases)  
  tab year region, matcell(total)
  </code></pre>
  
  <p>Both matrices are 10 columns by 9 rows. 
  I now want to create a new matrix with percents which<br>
  equals:  p = (cases/total)*100</p>
  
  <p>But I cannot find the command to do so in Stata? is there an easy way? </p>
