The main expense is in quadratures. ONe also needs to precompute and tabulate the inverses. I could show Grisouard how to speed it up some. * I follow Nick Trefethen, Spectral Methods in MATLAB, Chapter… text/html 2010-07-07T01:34:37-07:00 Predrag Cvitanovic http://www.channelflow.org/dokuwiki/doku.php/chaosbook:stability?rev=1278491677&do=diff <- chaosbook (ChaosBook.org blog, chapter Local stability) --- Predrag Cvitanovic 2009-02-11 12:55 Enter latest posts at the bottom - flows better. :?: Is that Schwarzenegger quote at the beginning of section 4.2 something he actually said?

There exist also orthogonal Rice polynomials (hypergeometric functions) but I think they are not related to the Rice distribution. text/html 2010-07-02T04:56:23-07:00 Predrag Cvitanovic http://www.channelflow.org/dokuwiki/doku.php/chaosbook:getused?rev=1278071783&do=diff <- chaosbook (ChaosBook.org blog, chapter Why cycle?) --- Predrag Cvitanovic 2010-07-02 Blog Predrag 2010-07-02 John Elton resurfaces, at Cornell, with a very non-ChaosBook.org version of Fluctuations in classical sum rules (he did that as REU student with Tomsovic a number of years ago). text/html 2010-06-25T09:40:41-07:00 Predrag Cvitanovic http://www.channelflow.org/dokuwiki/doku.php/chaosbook:inter?rev=1277484041&do=diff <- chaosbook (ChaosBook.org blog, chapter Intermittency) --- Predrag Cvitanovic 2009-01-01 Remarks Predrag 2010-06-25 Separation of trajectories and its Relation to Entropy for Intermittent Systems with a Zero Lyapunov exponent by Nickolay Korabel and Eli Barkai looks interesting... text/html 2010-06-25T09:17:41-07:00 Predrag Cvitanovic http://www.channelflow.org/dokuwiki/doku.php/chaosbook?rev=1277482661&do=diff <- research blogs forum for ChaosBook.org discussions (an experiment in progress) How to ... * How to login * How to blog * How to proofread * To do * Kvetch here ChaosBook chapters * Overture * Go with the flow * Discrete time dynamics * Local stability * Get straight * Hamiltonian dynamics * Billiards * World in a mirror * Relativity for cyclists * Charting the state space * Stretch, fold, prune * Fixed points, and how to get them * Walkabout: Tr…
