Very new to Sage. Think it is installed correctly and I am using the Notebook interface. Trying to run the meijerg that is supposedly in mpmath but it complains that it can't find the function. I did import mpmath but did not get a response to that command Do I need to download something else? What can I do to get meijerg working (and need to plot)?

Do 'normal' sage commands like `2+2` work? If so, then @DSM's answer should work.

(Hint: when reporting a problem, it's best to cut and paste exactly what you did and any error messages so that we can see where the problems are.)

It seems to work for me:

sage: import mpmath
sage: mpmath.meijerg([[],[]], [[0],[0.5]], (1/2)**2)
sage: (cos(1)/sqrt(pi)).n()

In the notebook you won't have the "sage:" bits at the start, but it should give you the same results. Alternatively, you could use

from mpmath import meijerg

and then you wouldn't have to add the "mpmath." bit at the start.
