[Numpy-discussion] Permutations in Simulations`

[Mark Janikas]

Hello All,

I want to create an array that contains a column of permutations for each simulation:

import numpy as NUM
import numpy.random as RAND
x = NUM.arange(4.)
res = NUM.zeros((4,100))

for sim in range(100):
res[:,sim] = RAND.permutation(x)


Is there a way to do this without a loop?  Thanks so much ahead of time...

MJ
