Thanks. That works well for x. How to do the same for gamma and
log(gamma)? In ipython I get the following:
In [1]: from sympy import *
In [2]: from sympy.abc import mu, gamma, x
In [3]: f = (- gamma * (x-mu)**2 - log(gamma) + log(2*pi)) / 2
In [4]: g1 = Wild('g1', exclude=[gamma])
In [5]: g2 = Wild('g2', exclude=[gamma])
In [6]: g3 = Wild('g3', exclude=[gamma])
In [7]: print f.expand().match(g1 * log(gamma) + g2 * gamma + g3)
None
So it looks like this method only works for polynomials but not when I
want to factor in terms of more complicated functions like log(gamma).
Am I missing something?
Thanks for the help so far,
John.
