Re: [Bug 106757] Re: scilab gives wrong results
Thank you for your message. I have installed scilab from the ubuntu repository now and I could not reproduce the bug. So I guess that means it works now.

[Bug 106757] scilab gives wrong results
Public bug reported: Binary package hint: scilab I encountered the following bug when running the attached scilab program test.sci in scilab 4.0: --A=[1,0.5;0.5,1]; --[U,S,V]=svd(A); --B=U*S*V' --A-B gives --B=U*S*V' B = 0. 0.5 0.50. --A-B ans = 1.0E-15 * 0.22204460.3330669 0. 0.1110223 As you can see, the value for B is wrong, since B should equal A. On the other hand A-B is practically 0. The problem occured on two different platforms (running ubuntu) using the debian package. However, it does not occur in scilab 4.1 as downloaded from www.scilab.org, i.e. here we get the correct answer for B --B=U*S*V' B = 1. 0.5 0.51. --A-B ans = 1.0E-15 * 0.22204460.3330669 0. 0.1110223 I have reported this to Torsten Werner, the dedian-package maintainer, who said that he knew that the scilab package in ubuntu is completely broken, but that there is no problem of that sort on a debian platform. ** Affects: scilab (Ubuntu) Importance: Undecided Status: Unconfirmed -- scilab gives wrong results https://bugs.launchpad.net/bugs/106757 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list [EMAIL PROTECTED] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
