Dear Aaron,
your suggestion did work, HOWEVER i had to upgrade sympy to 1.0. It did
nothing on 0.7.6 (the default one on ubuntu 16.04)
only writing here to "document" this behaviour
regards

Dear List,
i am writing since i would like to define the output of the derivative of a
function, and i don't have a clue of how to achieve it
to explain what i wish to do, let's consider the following script
from sympy import *
u = symbols('u')
der = symbols('der')
e = symbols('e',

Dear list,
i am a newby to sympy, and i should say that i liked what i found, so ...
first of all kudos to the developers.
as of now i can succesfully generate my finite element matrices using
sympy, which saves me quite a lot of work.
the point is that now i would like to optimize a bit what
10 matches
