Oops, i just see that your original example was x=pi/2, y=pi. That is
fine:
sage: m(pi/2,pi)
[0 0]
[0 0]
and is of course better than going via RR:
sage: m(RR(pi/2),RR(pi))

Interesting. I tried the example in 2.11 and ran into problems with the
very first line:

If you note carefully, the slides switch from being about "Let's use
Sage" to "Let's use Sage++" between Demos 5 and 6, which would
validate John's suspicion. In a slightly older version than Jason's I
have neither MacDonald nor Jack Polynomials, and of course not Poset,
and apparently not "@man
Hello everyone.
I'm sorry to reply in so late on this, things have been busy and I've
not been keeping up with the list lately.
As for my slides: all included examples do work in Sage or "Sage++",
where Sage++ denotes a future version of Sage. The upshot is that
there is some code to add support

In what version of Sage was n implemented for matrices? Right now,
N(m) gives an error in my version 2.9.2
sage: N(m)

This is *only* in Sage-3.0, which hasn't been released yet. There you
will be able to do:
sage: m = matrix([[2

Hello,
Sage already has two decorators that provide this functionality.
@func_persist will remember the computed values across Sage sessions
since the results are written to a file
@CachedFunction just stores the results in memory
Note that all of the arguments to the function whose results you

I ran across the following post and thought I would pass it along.

For those of us who were weened on Maple, the post describes a very
nice way to get the "options remember" functionality that is built
into Maple in python (and
