Hi,
I want to concatenate two numpy arrays with shape (n1,n2) and (n1,n3)
into a single array with shape (n1,n2+n3). I guess there is an elegant
way to do this but I couldn't figure it out. So any help is very much
appreciated.
Regards
Rolf

Suppose a1.shape is (n1,n2)
and a2.shape is (n1,n3)
Then you want to do
a3 = concatenate((a1 ,a2),axis=1)
or equivalently
a3 = hstack([a1,a2])
a3 = r_['1',a1,a2]

I'm new to python and want to use it for an assignment.
I have succesfully implemented a galois field class including the _repr__,
__mul__, __div__, __add__ and __sub__ methods. Basically a galois field is
an integer modulo a prime number. Now I want to make a matrix of these
galois field objects using the numpy library....

last week I posted a problem with running out of memory when changing

I was able to reduce the code (see below) to its smallest size and
still
have the problem, albeit at a slower rate. The problem appears to come

How do you print a numpy array?
I tried the obvious print a, print `a`, and print str(a), but
none of them work on anything other than trivially small
