 % Sparse coding of a group of signals based on a given 
 % dictionary and specified number of atoms to use. 
 % input arguments: Dict - the dictionary
 %                   X - the signals to represent
 %                   m - number of atoms in Dictionary

 % optional:         if Dict is function handle then Transpose Dictionary
 %                   handle needs to be specified.
