<h2><a name="_description"></a>DESCRIPTION <a href="#_top"><img alt="^" border="0" src="../../up.png"></a></h2>
<div class="fragment"><pre class="comment"> MYRANDINT(M,N,RANGE) is an M-by-N matrix with random integer entries 
 drawn with replacement from elements of vector RANGE.  The elements in
 vector RANGE do not need to be contiguous or unique.  (Actually, they do
 not even need to be integers: The function works the exact same way with
 noninteger elements, but a warning is generated to alert the user that 
 noninteger elements are being sampled.) 

 To specify a contiguous integer range from Xlow to Xhi, use RANGE = [Xlow:Xhi].  
 
 MYRANDINT(M,N,RANGE,'noreplace') is an M-by-N matrix with random integers 
 drawn without replacement.

 This function is based around RAND and RANDPERM, and is intended as a
 modest imitation of Comm Toolbox's RANDINT.</pre></div>
