title: avoid matrix inverse warning in matlab
body: <p>I'm working with 6x6 matrices which have varying precisions of data. When I try to inverse that matrix in MATLAB I usually get <code>Inf</code> or <code>NaN</code> as all the data and MATLAB throws a warning:</p>
  
  <blockquote>
    <p>Matrix is singular to working precision. </p>
  </blockquote>
  
  <p>Is there anyway to avoid it and get proper results?</p>
