[Scilab-users] Obsolete

[Calixte Denizet]

Hi Claus,

The power of a matrix is defined for square matrices so since a vector 
with size strictly greater than 1 is not a square matrix we decided to 
emit a warning in this case.
We took this decision because this "feature" (ie [1 2 3]^2 <==> [1 2 
3].^2) was confusing for students.
So if you want to avoid the warning, you should replace v^2 by v.^2 when 
v is a vector.

Best regards,

Calixte
