Hi,

I have a (n,2) shaped array representing points and I would like to

double each point as in:

A = np.arange(10*2).reshape(10,2) B = np.repeat( A, 2, axis=0 )

Is it possible to do the same using 'as_strided' to avoid copy (and still

get the same output shape for B) ? No, this would not be uniformly strided in the 0 axis. -- Robert Kern
