Hi,

Using Scilab 5.4.0 on Linux, I wanted to calculate the square of a 3x3 
matrix, and instead of 
following the rules of linear algebra by doing A11*A11+A12*A21+A13*A31 
for the (1,1) element of the result, Maxima just arithmetically squared 
each element of the matrix. A multiplication of 2 unequal matrices did go 
well btw. So how do I get the correct square of a matrix?

Thanks
