 Usage:  {g, gind} = groupcol (col, ncol)  

 

 Input:



  col                    scalar or color vector 

                         

  ncol                   scalar expected length of colorvector 

                         

 Output:



  gcol                   m x 1 different colors 

                         

  gind                   n x 1 index of groups
