title: Cellfun : How to sum each row in a cell array of matrices? Matlab
body: <p>Say I have 3x3 cells, each cell containing a matrix of 9x9, how would I go about using cellfun to sum each row of the entire cell array?</p>
  
  <p>I keep obtaining the error ''bad cell reference'' when I try to use the : in the curly brackets.</p>
  
  <p>I'd rather not convert it to a matrix then back to cells again.</p>
  
  <p>Many thanks for your wisdom guys!</p>
