Since no-one has done Octave yet, I'll go ahead and do it (along with MATLAB for comparison). I can't do SciLab or R because I don't know how to use those

MATLAB 2012b:
Code:
>> N = dlmread('N.dat');
>> d = dlmread('d.dat');
>> tic ; r = N \ d; toc
Elapsed time is 0.797772 seconds.
GNU Octave 3.6.2:
Code:
octave:1> N = dlmread('N.dat');
octave:2> d = dlmread('d.dat');
octave:3> tic ; r = N \ d; toc
Elapsed time is 0.624047 seconds.
This is on an Intel i5 (2 core + hyperthreading) with Linux as the host OS (kernel version 3.7.6).
