short of symbolic manipulation (e.g. maple), all we do is discretize and approximate, right?
Integration (aka quadrature) is "easy" but numerical diff is very unstable. ODEs solve well w/ Runge-Kutta methods. ________________________________ From: [email protected] [[email protected]] on behalf of David Shaffer [[email protected]] Sent: Sunday, August 05, 2012 5:13 PM To: [email protected] Subject: Re: [Pharo-project] Differential and Integral calculus in Pharo?

Or any place that I can take a look at? Thanks in advance! Cheers In case you haven't already come across it: http://sourceforge.net/projects/dhbnumerics/ In my personal experience the algorithms in the book are often naive and problematic compared to industrial-strength numerical algorithms but they are also quite often good enough for a first attempt at some numerical work.
