Hi,
Numpy let's me define arrays with zero rows and/or
columns, and that's wanted behaviour from what I have
read in discussions. However, I can add an array
with zero rows to an array with one row (but not more),
resulting in another zero row array, like so:
In: a = zeros((4,0))
In: a
Out: array([], shape=(4, 0), dtype=float64)
In: b = zeros((4,1))
In: b
Out:
array([[ 0.],
[ 0.],
[ 0.],
[ 0.]])
In: a + b
Out: array([], shape=(4, 0), dtype=float64)
Is this a bug? This should give a shape mismatch error,
shouldn't?
Cheers
David
