New issue 1835 by smichr: 1835: coeff changes http://code.google.com/p/sympy/issues/detail?id=1835 1835: coeff changes coeff now uses extract multiplicatively to find terms containing the quantity of interest. There is no longer an expand option needed; if you want the result expanded, use expand(eq.coeff(term)). It can also handle Add terms, e.g. >>> (2*x*(1+x)).coeff(1+x) 2*x There is an exact option (on by default) which only returns what a 'term' can be extracted from once. If this option is off, then partial matches result: >>> (x+x**2).coeff(x) 1 >>> (x+x**2).coeff(x, exact=0) 1 + x Because it depends on extract_multiplicatively, it also works with noncommutatives. -- You received this message because you are listed in the owner or CC fields of this issue, or because you starred this issue.
