Maxima is able to solve some type of inequalities (see http://cadadr.org/maxima/faq.html).<br><br>(%i1) load(fourier_elim)$<br>(%i2) fourier_elim([(x/(x-3))<4],[x]);<br>(%o2) [4 < x] or [x < 3]<br>(%i3) fourier_elim([((x-a)/(x+a))>0],[x]);<br>(%o3) [max(- a, a) < x] or [x < min(a, - a)]<br>(%i4) <br><br>There is a scilab toolbox that will allow you to access maxima within scilab: http://forge.scilab.org/index.php/p/scimax/. But its only available for the linux version of scilab at this time. I haven't used it, so I can't tell you much about it.<br><br>If you're not using Linux, you might want to take a look at installing ubuntu or one of the other linux distributions on VirtualBox. This will allow you to use Linux within Windows.<br><br>HTH,<br>Stephen<br><br><div><div id="SkyDrivePlaceholder"></div>> Date: Wed, 9 May 2012 20:13:39 -0700<br>> From: viniciussucupira@gmail.com<br>> To: users@lists.scilab.org<br>> Subject: [scilab-Users] Inequality<br>> <br>> I would like please a solution in Scilab to [(x-a)/(x+a)]>0<br>> <br>> Answer: x^2>a^2 or |x|>|a|<br>> <br>> http://mailinglists.scilab.org/file/n3975979/IMAGE.jpg <br>> <br>> <br>> <br>> <br>> --<br>> View this message in context: http://mailinglists.scilab.org/Inequality-tp3975979.html<br>> Sent from the Scilab users - Mailing Lists Archives mailing list archive at Nabble.com.<br>> <br>> --<br>> To unsubscribe from this mailing-list, please send an empty mail to<br>> users-unsubscribe@lists.scilab.org<br>> To check the archives of this mailing list, see<br>> http://mailinglists.scilab.org/<br>> <br></div> </div></body>
