[Numpy-discussion] Matlab -> NumPy translation and indexing

[David Koch]

Hi,

so one thing I came across now is the following, very simple:

Matlab:
A = []
while ....
    A = [A some_scalar_value]
end


In Python, I tried:

A = empty((0,0))
while ....
    A = concatenate((A, array([someScalarValue])), 1)
end

which returns an error since the shape of the empty A does not match the
vector I want to concatenate with. Any way to get around this without having
to use some obscure "if exist A" clause. I am still stuck in my Matlab ways
- hoping to get rid of them though.

/Thanks,

David
