Hi,
I'm running sage 4.6.1 and cannot use plot after loading mpmath.
Namely, running
from mpmath import *
plot(lambda t: sin(2*pi*t), [1, 4])
produces no output in the notebook. I'm loading mpmath because I need
to make plots of theta functions, and the page
http://mpmath.googlecode.com/svn/trunk/doc/build/functions/elliptic.html#jacobi-theta-functions
tells me to first run "from mpmath import *" to gain access to jtheta.
Presumably this is a bug?
It's working exactly according to design. The problem here is that the
mpmath plot overwrote the Sage plot. In general, it's discouraged to do
an "import *". Instead, try doing this:
sage: import mpmath
then prefix each mpmath command with "mpmath":
sage: mpmath.jtheta(1, 0.25, '0.2')
mpf('0.29451207986273')
Thanks,
Jason
