Comment:
I made my own tests running the following code:
{{{
#!python
for i in [2, 3, 4, 5, 7, 9, 11, 16]:
K = GF(i, "z")
for j in [100,200,300,500,1000]:
M = random_matrix(K, j, j)
bool(M)
M *= 0
bool(M)
}}}
without the patch:
{{{
5 loops, best of 3: 3.68 s per loop
}}}
with the patch:
{{{
5 loops, best of 3: 2.29 s per loop
}}}
So there is some speedup. Code looks harmless and tests pass. Positive
review!
