So, x is known before you start?
How big is N? Also, is y.shape (N,)?
Do you need al

Does anyone know how to efficiently implement a recurrence relationship
in numpy such as:
y[n] = A*x[n] + B*y[n-1]
Thanks,

Hi,
I stumbled across this anomaly, the assignment to ncycle[i][b] fails,
yet ncycle[:][b] works and the final print works. Is this a known bug
or limitation ? I am running numpy-1.2.1 with python 2.5.4

from numpy import *
ncycle = arange(10)
i = array([0, 1, 2, 3, 4, 5
