CELLMULT is the jCell module of jLab.

 CELLMULT  Multiplication acting on each element in a cell array.
 
    Z=CELLMULT(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 products, 
 
        Z{1}=X{1}.*Y{1}, Z{2}=X{2}.*Y{2},..., Z{N}=X{N}.*Y{N}.
 
    X may also be a scalar or an array of N=LENGTH(Y) numbers. 
 
    Usage: z=cellmult(x,y);
