An error will show if the matrices have invalid dimensions for multiplication.

{{trans|Mathematica}}
[1,2; 3,4; 5,6; 7,8] → m1
[1,2,3; 4,5,6] → m2
m1 * m2
Or without the variables:
[1,2; 3,4; 5,6; 7,8] * [1,2,3; 4,5,6]
The result (without prettyprinting) is:
[[9,12,15][19,26,33][29,40,51][39,54,69]]
