FYI, in Octave 3.2.4 same test took 31 ms - 27 times faster then above best

Here are also some other simple linalg tests on same matrix (in seconds):

| fun | ATLAS    | MKL      | OCTAVE    |
|-----|----------|----------|-----------|
| svd |  30.9    |  14.3    |   6.844   |
| inv |   7.41   |   2.74   |   1.906   |
| eig | 116      |  25.2    |  45.05    |
| det |   2.55   |   0.855  |   0.5469  |
