NumPy array initialization (fill with identical values)
I need to create a NumPy array of length n, each element of which is v.
Is there anything better than:
a = empty(n)
for i in range(n):
a[i] = v
I know zeros and ones would work for v = 0, 1. I could use v * ones(n), but it won't work when would be much slower.v is None, and also
