title: How to store the character for each looping in Matlab?
body: <p>I have a string :</p>
  
  <pre><code>A="ILOVEYOUMATLAB"
  </code></pre>
  
  <p>and I create 2 empty array:</p>
  
  <pre><code>B1=[]
  B2=[]
  </code></pre>
  
  <p>when i used the while loop, for the first time looping, if i want the first character from the <strong>A</strong> to store in <strong>B1</strong> array, what command i need to write?</p>
  
  <p>if in Python, i just need to used <strong>append</strong> command, but if in Matlab, what is the commend need to apply?</p>
