[Numpy-discussion] Initializing an array to a constant value
Mon Feb 13 07:30:04 CST 2012
I have a pretty silly question about initializing an array a to a given
scalar value, say A.
Most of the time I use a=np.ones(shape)*A which seems the most
widespread idiom, but I got recently interested in getting some
I tried a=np.zeros(shape)+A, based on broadcasting but it seems to be
equivalent in terms of speed.
Now, the fastest :
a = np.empty(shape)
but it is a two-steps instruction to do one thing, which I feel doesn't
look very nice.
Did I miss an all-in-one function like numpy.fill(shape, A) ?
