title: use variable as integer in GA tool box
body: <p>I am solving an optimization problem for the optimal placement of piezoelectric patches over a cantilevered plate using GA tool box in MATLAB2009b.</p>
  
  <p>There is a variable which varies from 1 to 64. I want the GA to take this variable as an integer only, and not as a real number because due to real number having time period for one run increases. Any suggestions?</p>
