Numpy Adding two vectors with different sizes

Question

If I have two numpy arrays of different sizes, how can I superimpose them.

a = numpy([0, 10, 20, 30])
b = numpy([20, 30, 40, 50, 60, 70])

What

Answer 1

If you know that b is higher dimension, then:

>>> a.resize(b.shape)
>>> c = a+b

is all you need.
