From octave-sources-request at bevo dot che dot wisc dot edu Mon Apr 10 12:30:52 2000 Subject: new polyder From: Kai Habel To: octave-sources at bevo dot che dot wisc dot edu Date: Mon, 10 Apr 2000 19:29:27 +0200 Hello, I have added support for polynomial products and quotients to polyder. It should work like the matlab function now. polyder doesn't call polyderiv anymore, but it includes the polyderiv code for polynoms, so you can replace the old script with the new one. A patch wouldn't be smaller, so I send the complete file. I have written some new functions (trapz.m cumtrapz.m legendre.m). They should work like their matlab counterparts. The legendre script needs a bit of improvement, it works up to degree 40, then the result become instable. I will try to improve the algorithm, to avoid the calculation of large factorials. You can find the new functions at my homepage in the others section. You can also find a tarball including my octave scripts. http://users.berlin.de/~kai.habel Bye -- Kai Habel mailto:kahacjde at linux dot zrz dot tu-berlin dot de ----------------------------------------------------------------------- Octave is freely available under the terms of the GNU GPL.
