[Numpy-discussion] building an array using smaller ones

[Rudolf Sykora]

Hello everybody,
I wonder how I could most easily accomplish the following:

Say I have sth like:
a = array( [1, 2] )
and I want to use this array to build another array in the following sence:
b = array( [[1, 2, 3, a], [5, a, 6, 7], [0, 2-a, 3, 4]])  # this doesn't
work

I would like to obtain
b = array( [[1, 2, 3, 1, 2],  [5 ,1 ,2 ,6 ,7], [0, 1, 0, 3, 4]] )

I know a rather complicated way but believe there must be an easy one.
Thank you very much.

Ruda
