confusionmat

Hi, here you have my implementation of the confusionmat function. I hope it helps someone

 function [ret] = confusionmat(v1, v2)
    values = union(unique(v1), unique(v2));
    ret = zeros(size(values), size(values));
    for i = 1:size(v1)
       i1 = find(values == v1(i));
       i2 = find(values == v2(i));
       ret(i1, i2) = ret(i1, i2) + 1;
    end
 endfunction

Hi! Thank you for the patch but we don't really use the Octave wiki as discussion forum and almost no one is following this. You really should be submitting this on Octave's patch tracker.

Octave 3.6

Thanks for working on this very useful package! I'm still on octave 3.6.4 (fedora 20); statistics 1.2.3 requires Octave (>= 3.6.1) io (>= 1.0.18) but io 2 requires octave 3.8. Is io-1.2.5.tar.gz (the latest 1.x) the best choice to satisfy the dependency? 93.50.129.38 03:46, 7 March 2015 (PST)
