hi,
slightly off-topic, but still regarding the speed differences... what's
the difference between the following 2 functions?
numpy.linalg.solve
scipy.linalg.solve
the first is almost 2 times faster on the same data (4096 repetitions of
a A*a = b problem with A = 2x2 float32 matrix) - typically 0.30 vs. 0.57
sec for the whole operation...
best,
