title: How to delete row with a certain string in matlab
body: <p>Another problem, that i would like to solved, if  i have string array:</p>
  
  <pre><code>A= [001   0
  111    5
  234    6
  000    0
  101    5]
  </code></pre>
  
  <p>a 5x2 array with zero string at column 2, i want to delete rows containing zero at column 2, </p>
  
  <p>i tried using </p>
  
  <pre><code>A(A&gt;0)=0
  </code></pre>
  
  <p>but it doesn't work</p>
  
  <p>see desired output below:</p>
  
  <pre><code> A= [111    5
      234    6
      101    5]
  </code></pre>
  
  <p>so as you can see 000, and 001 was deleted because they have zero in column 2, so how i would do that? thanks</p>
