Operations with unknown values don`t return unknown values

[César Pérez Álvarez]

Hi!

If we try these lines of code:

Matrix a = Col(?,1,9);
Matrix b = Col(10,9,1);

Matrix c1 = Tra(a)*b;
Matrix c2 = a+b;
Matrix c3 = a-b;
Matrix c4 = Min(a, b);
Matrix c5 = Max(a, b);

We can see that c1 is a 1x1 matrix with value 18 (* operates with unknown value like a zero value). In c4 and c5, operations with unknowns don't return unknowns.
I don't know if exist another functions with this problem.
