title: gmdistribution.fit and .mat files
body: <p>I've a very large .mat file which contains a lot of data which I need to visualize. .mat file contains 5 row with each row containing 1x5 matrix - which contains the data. I need to concatenate specific rows together, then apply gmdistribution.fit to it. I'm not sure as to how exactly I access specific elements of the .mat file to concatenate them together.</p>
  
  <p>Say I wish to concatenate first row - > 1st row with 2nd row - > 1st row. How would I go about doing this? I'm new to matlab and finding it difficult to grasp it.</p>
  
  <p>Also, could you explain gmdistribution.fit, please? I read the documentation in their website, however, I still am not exactly sure about the parameters. </p>
  
  <p>Thankyou for your help.</p>
