title: Matlab, matrix containing random numbers within specified range
body: <p>I am absolutely new to Matlab and am trying to create an m-by-n matrix containing numbers within a specified range (ie. between -1 and 1). </p>
  
  <p>Is there an equivalent function to <code>rand(m, n)</code> where I can specify the range myself or would I need to explicitely create a bunch of random numbers (as ie. was described in this <a href="https://stackoverflow.com/questions/1860823/generate-a-random-number-within-a-range">answer</a>) and create a matrix from them?</p>
  
  <p>Any pointers to relevant Documentation, etc. highly appreciated.</p>
