Comment (by rbeezer):
My 2 cents.
1. I like that large matrices do not get printed entirely without being
requested explicitly.
2. Even with a helpful message, I see students who wonder why they do not
get the whole matrix. So I would rather not see the bare output
{{{
20 x 20 dense matrix over Rational Field
}}}
3. I think it is less important to see the actual name of the matrix
parroted in the output (the source of the inefficiency here). So
something like the following would be sufficient in my eyes, if it was
easier to code/maintain:
{{{
20 x 20 dense matrix over Rational Field (use the '.str()' method to see
all of the entries)
}}}
Thanks for cleaning this up.
