MATLAB: Cell Array and Matrix

Question

How do I multiply/subtract a cell array and a matrix for Ex. I want to multiply D and L , Cell array

D = {[1 2] , [1 1] ; [1 6 ] , [5 2]  };

and matrix

L=[1 0 0 0; 0 1 0 0 ]

Answer 1

One of the possibilities

D = {[1 2],[1 1] ;[1 6 ],[5 2]}
L=[1 0 0 0; 0 1 0 0 ]; 
out=cellfun(@(x) x*L,D,'un',0)

%or maybe

cell2mat(D).*L
