Hi, I'm sure this is straightforward enough yet I've not managed to work out how to do it so far from the documentation. I've asked this question on the maxima mailing list and I believe it can do what I want. However I do most of my work in python and would much prefer a python based solution. Can sympy provide this? I've tried to use matching but to no avail.
I have several functions of several variables, for instance, f(x, y, z) which I know can be written in the following form: f(x, y, z) = g1(y, z) * h1(x) + g2(y, z) * h2(x) + g3(y, z) * h3(x) where h1(x), h2(x) and h3(x) are known. How to get sympy to produce g1(y, z), g2(y, z) and g3(y, z)? For instance f(x, mu, gamma): (- gamma * (x-mu)**2 - log(gamma) + log(2*pi)) / 2 So how can I ask sympy to decompose f as: g1(mu, gamma) * x**2 + g2(mu, gamma) * x + g3(mu, gamma) and g1(x, gamma) * mu**2 + g2(x, gamma) * mu + g3(x, gamma) and g1(x, mu) * log(gamma) + g2(x, mu) * gamma + g3(x, mu) Thanks in advance, John. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
