title: MATLAB read multiple excel files
body: <p>I want to compare between 20 files. How can I access them without making 20 variables. I tried making an array but from some reason it doesn't recognize the number.</p>
  <pre><code>for i=1:20
       m=strcat(char(i),&quot;.csv&quot;);
       t(i)=readtable(m);
  end
  </code></pre>
