MATLAB: Remove zero entries from cell arrays

cell arraydeletefindismemberlocateremovezeros

Suppose I have a m x n cell array. Some of these cells contain a 1 x 2 matrix of values other cells contain just a zero. I want to be able to delete all cells that contain zeros and have the cell array automatically re-size when finished. If you copy and past this in the command window you can see what I'm trying to accomplish. I've tried using ismember to look for the zeros but had no luck. I'm not very good when it comes to doing operations on cells. I need this to remain a cell array also. Thanks for any help.
