title: Removing rows and columns from matrix in Matlab
body: <p>How should we efficiently remove multiple line and columns from a matrix in Matlab?
  A vector holds indices that should be removed.</p>
  
  <p>Input: t by t matrix</p>
  
  <p>Output: (t-k) by (t-k) matrix in which k non-adjacent rows and corresponding columns are removed from input matrix.</p>
