title: matlab engine "Can't start MATLAB engine"
body: <p>The following code:</p>
  
  <pre><code>   if (!(ep = engOpen("\0"))) {
        fprintf(stderr, "\nCan't start MATLAB engine\n");
        return EXIT_FAILURE;
     }
  </code></pre>
  
  <p>Gives:</p>
  
  <pre><code>Can't start MATLAB engine
  </code></pre>
  
  <p>I don't know what is the reason ... I have two versions of Matlab R2011a 64-bit, and R2010b 32-bit. I use engine lib of second version of matlab. OS windows 7 x64.
  According to some topics this problem can be caused by multiple matlab versions
