W2K, 850MHz PII laptop. Interesting to see that the 1.1 GHz Athlon is a factor
of 2 faster.
Finding matrix determinant
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.30 | 0.56 | 0.30 | 0.63 (secs for 2000 calls)
100 | 0.72 | 2.59 | 0.74 | 2.78 (secs for 300 calls)
500 | 1.06 | 3.77 | 0.98 | 3.93 (secs for 4 calls)
.
Solving system of linear equations
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.50 | 0.47 | 0.48 | 0.53 (secs for 2000 calls)
100 | 0.89 | 2.45 | 0.82 | 2.69 (secs for 300 calls)
500 | 1.11 | 3.67 | 0.95 | 3.85 (secs for 4 calls)
.
Finding matrix inverse
==================================
| contiguous | non-contiguous
----------------------------------------------
size | scipy | Numeric | scipy | Numeric
20 | 0.65 | 1.04 | 0.67 | 1.11 (secs for 2000 calls)
100 | 2.16 | 8.38 | 2.13 | 8.61 (secs for 300 calls)
500 | 2.62 | 22.03 | 2.60 | 22.29 (secs for 4 calls)
