[Numpy-discussion] hstack

The problem is that hstack needs a tuple as argument:

x = ones( (9,1) )
y = zeros( (9,2) )
z = hstack( (x,y) )

Notice the parenthesis in the arguments.

Hello,

When I try to use the command hstack, I am given the error message
"TypeError: hstack() takes exactly 1 argument (2 given)". I have a 9X1
array (called array) that I would like to concatenate to a 9X2 matrix
(called matrix), and I try to do this by typing the command
hstack(array,matrix). I would appreciate any help in getting this to
work.

Thanks,

Stephanie
