title: 3d plotting of a 2d matrix in matlab
body: <p>I have an MxN matrix, Z, and some variable h.  This matrix represents the points to a solution of a function f(x,y).  h is the spacing between points.  For instance:</p>
  
  <pre><code>Z(x/h,y/h) = (some value in the Z direction), where x and y are some multiple of h
  </code></pre>
  
  <p>The domain is from 0 to M*h and the range is from 0 to N*h.  I would like to make a 3d representation of the solution defined by the matrix.  The graph should be similar to what is produced using the pdetool.  How do I do this in Matlab?</p>
