Actually, I think it's likely to be (much) faster for the same accuracy, since you can use a bigger step size. But of course, it's a little bit more programming. > I mean, you have to understand that for many problems in scientific > > computing, the matrices are large enough that you really want to bust > > out C and fortran libraries. Indeed. But scientific computing needs vary a lot, from the stuff you do with a calculator and the back of an envelope, to the really hard problems that require supercomputers. And as hardware (and javascript) gets faster, the boundaries keeps moving, and you can do more with simple means as time passes. - Harald -- -- Job Board: http://jobs.nodejs.org/ Posting guidelines: https://github.com/joyent/node/wiki/Mailing-List-Posting-Guidelines You received this message because you are subscribed to the Google Groups "nodejs" group.
