Without understanding anything, this seems to work:
jo...@johan-laptop:~$ python
Python 2.5.4 (r254:67916, Feb 18 2009, 03:00:47)
[GCC 4.3.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> import numpy as np
>>> a = np.array([1, 2, 3])
>>> b = np.zeros((5, 3))
>>> b[:, :] = a
>>> b
array([[ 1., 2., 3.],
[ 1., 2., 3.],
[ 1., 2., 3.],
[ 1., 2., 3.],
[ 1., 2., 3.]])
Hope it helps
