[Numpy-discussion] chirp-z

All, I have been looking around for chirp-z code with a useable license. There is the original fortran version by Rader et. al. out there, as well as a package from FreeBSD at http://ftp2.at.freebsd.org/pub/FreeBSD/distfiles/fxt-2006.12.17.tgz. The latter is c++ and relies on function signatures

Re: [Numpy-discussion] Vista installer?

For the case in question, having the student set up his or her personal computer to work for the class (dual boot/Ubuntu) would probably be fine. Long term, though, I don't think Vista can be written off as a supported platform. If you're forced by your system admin to use it in a work environmen

[Numpy-discussion] IEEE floating point arithmetics

Hi all. I have to work with floating point arithmetics and I found a module called "double module" (http://symptotic.com/mj/double/public/double-module.html) that does what I'd like. Basically, I would like to find the nearest smaller and bigger floating point numbers, given a "real" real number (

Re: [Numpy-discussion] Median / mean functionality confusing?

Can I resurrect this thread then by agreeing with Chris, and my original post, that it would be better if median had the same behavior as mean, accepting axis and dtype as inputs? Best, Matthew On 5/24/07, Christopher Barker <[EMAIL PROTECTED]> wrote: > Sven Schreiber wrote: > >> (Zar, Jerrold H
