Question: Multiplying Two Matrices

Hi

I want to multiply two matrices

with(LinearAlgebra)

C:=<<1,1,2>|<-3,2,1>|<0,2,1>>;

E:=<<1,-1,3>|<-1,0,-2>|<2,3,0>|<3,-1,2>>;

MatrixMatrixMultiply(C, E);

Maple is not showing me the simplified form

The answer should be

 

4   -1 -7 6

-7 -5  8  5

4  0  7   3

Any suggestions?

Take care
