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...
