Hi Oguz,
You mentioned this problem:

It appears that the result is not being simplified.
For example a+a simplifies to 2*a, sin(0) simplifies to 0,
and a matrix multiplication A.B simplifies to the product
of A and B. Simplification is controlled by the variable "simp".
If simp is false, results are not simplified. Maybe simp is set
to false -- if you execute "simp;" what is the result?
Perhaps you can try a simpler problem such as ident(2).ident(2)
and tell us the result.
Can you also tell us what is the output of build_info(); ?
Thanks for your interest in Maxima, and I hope this helps.
