title: How to place columns of data set from excel file into numeric arrays
body: <p>I have an excel file that I grab by:</p>
  
  <pre><code>ds = dataset('XLSFile',fullfile('file path here', 'waterReal.xlsx'))  
  </code></pre>
  
  <p>It looks like this:</p>
  
  <p><img src="https://i.imgur.com/urgag7w.png" alt="Dataset content"></p>
  
  <p>I want each column in its own numeric array though! Like how when I load an example dataset: load carsmall, I get a bunch of individual numeric arrays. But I can't figure out how to do that.  </p>
  
  <p>I can do this individually by writing:</p>
  
  <pre><code>A = ds.TEMP, B = ds.PROD, ...
  </code></pre>
  
  <p>Bu what if I had  BIG excel file? What then?</p>
