* summary: [with algorithm, needs implementation] weight distribution
for binary codes => [with patch, needs review]
weight distribution for binary codes
Comment:
For an 1100 times speedup (which is the real point of not using Guava):
OLD:
sage: time C.spectrum()
CPU times: user 0.03 s, sys: 0.02 s, total: 0.05 s
Wall time: 3.36 s
[1, 0, 0, 7, 7, 0, 0, 1]
sage: time C.spectrum()
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 2.20 s
[1, 0, 0, 7, 7, 0, 0, 1]
sage: time C.spectrum()
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 3.26 s
[1, 0, 0, 7, 7, 0, 0, 1]
sage: time C.spectrum()
CPU times: user 0.02 s, sys: 0.01 s, total: 0.03 s
Wall time: 2.74 s
[1, 0, 0, 7, 7, 0, 0, 1]
NEW:
sage: timeit('C.spectrum()')
625 loops, best of 3: 1.86 ms per loop
