Dear People,
Is the function numarray.concatenate supposed to work for character
arrays? It doesn't for me. Do I need to write my own? Thanks in
advance. Please cc me, I'm not subscribed.
Faheem.
In [17]: foo
Out[17]:
CharArray([['T', 'T'],
['C', 'A']])
In [18]: bar
Out[18]:
CharArray([['G', 'G'],
['G', 'G']])
In [23]: numarray.concatenate((foo,bar))
