Hello,
While I am slowly learning Fricas, I noticed a pattern (or the lack of
it) that struck me as odd. Namely, some data structure types of fixed
size have constructors which take a parameter to define the size as
part of the type (e.g., SquareMatrix), while others (like Vector) do
not take a
Checkout the DirectProduct domain. Granted, this name might not be so obvious.
In a computer algebra system like FriCAS the name "Vector" should
probably be reserved for something with specific mathematical
properties. e.g. as in differential geometry.
But I think that there are some good

Thanks for taking the bait! :-)

Wow! That looks impressive. Kurt, I want that. Obviously you seem to
have connected the FriCAS
