Hi Aleks,
You can just treat m as any symoblic expression and call it as a function.
sage: x,y = var('x,y')
sage: m = matrix([[cos(x),0],[0,-sin(y)]])
sage: m
[ cos(x) 0]
[ 0 -sin(y)]
sage: m(x=1, y=2)
[ cos(1) 0]
[ 0 -sin(2)]
sage: m.variables()
(x, y)
sage: m(1,2)
[ cos(1
Hi everyone,
I wrote a Jacobian function for Sage, as follows:
def jacobian(fs, varz):
# Compute the derivatives of fs for each of the varz
# the number of columns is the length of vars
# the number of rows is the length of fs
numcols = len(varz)
numrows =

In Debian-based systems, it's the "alternatives" system. See

I've installed sage 2.11 on Kubuntu 7.10, and I'm poking around.
In the tutorial, sec 2.9.2 (?) there are 3D graphics examples using
jmol. When I run these (adding show(P) to the scripts) jmol reports
that it is starting, but all I get is a black rectangle with the
letters "jmol" in the lower

If you look at Franco's Sage talk (poseted here recently) he includes
a screenful of poset examples (on page 50, near the end of the
presentation) -- which in fact makes it look as if it's in Sage
already. So unless that page of the talk is wishful thinking, he must
have made some real progress t
