CELLDIV is the jCell module of jLab.

 CELLDIV  Division acting on each element in a cell array.
 
    Z=CELLDIV(X,Y) where X and Y are both cell arrays of N arrays, with the
    corresponding elements in X and in Y having the same size, returns the
    cell array Z containing their ratios, 
 
        Z{1}=Y{1}./X{1}, Z{2}=Y{2}./X{2},..., Z{N}=Y{N}./X{N}.
 
    One of X or Y may also be a scalar or a numeric array of the same 
    length as the other input argument.
 
    Usage: z=celldiv(x,y);
