title: Octave: How can I create a string made from 2 strings and a variable?
body: <p>I want to for-loop through some values and for each value of the index I want to save an image to the disk. Is there a way to achieve the following:</p>
  
  <pre><code>N = 16;
  name_RGB = ["RGBN" N ".jpeg"];
  
  imwrite(image1, name_RGB, "jpeg");
  </code></pre>
  
  <p>??</p>
  
  <p>So to explain, the loop is currently on index 16. I want to save an image with the name "RGBN16.jpeg". Anyone know if it is possible to join strings and variables together in Octave?</p>
