SCALAR AND MATRIX MULTIPLICATIONS

AE=8000000; %N
%Truss Lengths (m)
La=3; 
%Truss A
la=(3-0)/La;
ma=(4-4)/La;
matKeA=[ la^2, la*ma, -(la^2), -la*ma;
    la*ma, ma^2, -la*ma, -(ma)^2;
    -(la)^2, -la*ma, la^2, la*ma;
    -la*ma, -(ma)^2, la*ma, ma^2]
 
KeA= AE/La * matKeA

COMMAND WINDOW:

matKeA =

1 0 -1 0

0 0 0 0

-1 0 1 0

0 0 0 0

KeA =

1.0e+06 *

2.6667 0 -2.6667 0

0 0 0 0

-2.6667 0 2.6667 0

0 0 0 0

Why won't the scalar multiplication by applied to the terms in the KeA matrix?
