For me, this sounds good and seems to be a better solution than

What is the recommended way to extend sage classes? - I want to add
some functionality to the complex matrix class - specifically tests
for: is_symmetric, is_hermitian, is_unitary etc... you get the idea.
I have experienced and read that this is not so straightforward.
I guess I could do it by
Hi,
I'm a student in my final year of civil engineering and doing a thesis
concerning Sage and cryptography. As a part of my thesis I would like
to extend Sage and it's capabilities concerning boolean functions.
Right now I'm looking into making some representations available

By "extend" a Sage class it seems you mean "add a method to" a Sage class.
You want to know how to add a method to the class

Thanks David,
Yes extend by inheriting (and adding methods using the functionality
of the parent) is what I meant.
I think that gives me enough to get the job done... I'm sure the
is_symmetric method is usable as is - I just didn't spot it.
Cheers,
Simon

I saw similar tickets, now closed, but the problem remains in version
3.2:
x,y=var("x y")
plot3d(x^2-y^2, (-1,1),(-1,1))
There must be something wrong in the function
sage.plot.plot3d.parametric_plot3d.adapt_to_callable
My crude fix was:
try:
try:
if len(f):
Since
sage: x,y = var("x y")
sage: plot3d(x^2-y^2, (x,-1,1),(y,-1,1))
works fine, why not just use variables
sage: f = x^2-y^2
sage: f.variables()
(x, y)
to find the missing variables in plot3d(x^2-y^2, (-1,1),(-1,1))
and then replace the arguments (-1,1),(-1,1) by
(x,-1,1),(y,-1,1) in plot3d.

Hello folks,
over the next couple hours we hope to fix and merge all nine
outstanding issues for 3.2.1 - see
http://trac.sagemath.org/sage_trac/query?status=new&status=assigned&status=reopened&milestone=sage-3.2.1&order=priority
So feel free to pop into IRC and help out if you have some time. W

I've been experimenting with probability and found that in Sage, a
probability space is also a random variable by inheritance. This may be
useful. Without it, creating a random variable requires two classes: a
probability space and a random variable on that probability space.
Unfortunately, the ra
