By the way, I discovered another counter-example. Expressions like
a**2*conjugate(a)
are not transformed to
a*abs(a)**2
About the friendly treeview class, I agree and hope its coming soon :) is
it in the works?

needs to match whole expressions.

I think there is an error in the line (unbalanced paranthesis):
return node.xreplace ({e: S.One, conjugate(e): S.One})*abs(e)**2)
Yes, sorry, just remove
The unflatten_mul function factorized the 2, but not the g, i.e. it returns
2(g*|psi1|**2 + g*|psi2|**2)
instead of
2g*(|psi1|**2 + |psi2|**2)

I think
the receipts in this dicussion look very interesting.Maybe all of this
ones could be put in the official documentation.

Well yes, but that doesn´t change the fact that in Mathematica I can just do
expr /.{x_*Conj[x_] - Abs[x]^2}
and it just works!

Abs(a)**2*Abs(b)**2 + Abs(c)**2*Abs(d)**2
It does what I want if I apply it two times, though.

I define a function gamma with the following code:
from sympy import *
x = Symbol('x')
class gamma(Function): pass
Its latex representation is
print latex(gamma(x))
\Gamma\left(x\right)
whereas I would like it to be
\gamma\left(x\right)
i.e. lowercase instead of capital.
How can I achieve
Was this implemented into sympy at any point? It could be the equivalent of
Mathematica's CoefficientArrays function.

Hi guys,
I am having trouble translating a one-liner from Mathematica to Sympy. The
problem in question is explained in detail in this post:
