--- Begin Message ---Package: libruby1.8 Version: 1.8.2-9 Severity: important Ruby has a Matrix class in it's standard library that you can use with "require 'matrix'" -- handy! Except, it is totally broken; not only do a lot of things not work, but the things that "work" give incorrect results! Some examples: 1) It miscalculates the determinant: >> require 'matrix' => true >> x = Matrix[[3,-1,4],[2,5,1],[2,0,6]] => Matrix[[3, -1, 4], [2, 5, 1], [2, 0, 6]] >> x.det => 90 >> x.t.det => 126 Notice that not only is the determinant wrong (it should be 60), but the determinant of the transpose is wrong differently (det(A) == det(A^T)). 2) It doesn't do inversion right: >> x.inverse => Matrix[[0, 1, 0], [0, 0, 0], [0, 0, 0]] >> x.inverse.inverse ExceptionForMatrix::ErrNotRegular: Not Regular Matrix from /usr/lib/ruby/1.8/matrix.rb:595:in `inverse_from' from /usr/lib/ruby/1.8/matrix.rb:591:in `inverse_from' from /usr/lib/ruby/1.8/matrix.rb:580:in `inverse' from (irb):6 So, one, the inverse is totally wrong, but the inverse isn't invertable. This isn't just a fluke; I haven't got it to give the correct answer for ANY matrix I've tried. There are quite a few other things that are horribly broken. Anyway, it's nice to have a Matrix class, and having a Matrix class with some broken functionality isn't that bad, but it's *much worse* to have a horribly broken Matrix class that does the wrong thing and gives bad results. -- System Information: Debian Release: testing/unstable APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Shell: /bin/sh linked to /bin/bash Kernel: Linux 2.6.12-1-amd64-k8-sk98lin Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Versions of packages libruby1.8 depends on: ii libc6 2.3.5-6 GNU C Library: Shared libraries an ii libncurses5 5.4-9 Shared libraries for terminal hand ii zlib1g 1:1.2.3-4 compression library - runtime libruby1.8 recommends no packages. -- no debconf information
