Kisil <kisilv@maths.leeds.ac.uk> Date: Sun Nov 3 22:21:00 2013 +0200 Expansion rules for exp(), log(), and abs(). exp(a + b) -> exp(a)*exp(b) log(a*b) -> log(a) + log(b) abs(z*w) -> abs(z)*abs(w) log and exp are transformed only if expand_options::expand_transcendental is given. Signed-off-by: Vladimir V. Kisil <kisilv@maths.leeds.ac.uk> commit 5a3641098c88d3c6ea0765df65b801312ecfb91b Author: Vladimir V. Kisil <kisilv@maths.leeds.ac.uk> Date: Sat Nov 2 21:06:53 2013 +0200 Introduce expand_options::expand_transcendental. In general expand() treats the argument as a rational expression (and leave transcendental functions as they are). However sometimes it's convenient to expand transcendental functions too, like log(a*b) = log(a) + log(b) exp(a + b) = exp(a)*exp(b) Applying such transformation by default doesn't seem to be a smart idea (think of log(p^2/mu^2) transformed to 2*log(p) - 2*log(mu)). Therefore introduce expand_options::expand_transcendental. As the name implies expand() tries to transform transcendental functions only if this flag is set. Signed-off-by: Vladimir V.
