Ryan, could you please re-run this, without iterating? I want to eliminate the possibility that Matlab is optimizing out the iteration.

tic;
    r1 = N \ d;
t1 = toc;

// also save r1 to a file here so the computation is not optimized out.

disp(['Linear solver ' num2str(t1)]);


tic;
    r2 = inv(N) * d;
t2 = toc;

// also save r2 to a file here so the computation is not optimized out.

disp(['Invert and multiply ' num2str(t2)]);

Thanks.


PS - can someone with a working Octave installation please run this? also SciLab and R.
