title: How to get heat colors with plot3d in scilab?
body: <p>Hi this may seem to be a simple question but I am having a hard time understanding how to use the colors in a plot3d.</p>
  
  <p>That is what I have:</p>
  
  <pre><code>// x, y and z are matrix 4 by 100
  
  myColors = ones(1,size(z,2));
  plot3d(x,y,list(z,myColors),alpha=0,theta=270);
  </code></pre>
  
  <p>I would like to have myColors related to the altitude of z. </p>
