Hy everybody,
I'm wondering what is the (best) way to apply the same function to multiple arrays.
For example, in the following code:
from numpy import *
def f(arr): return arr*2
a = array( [1,1,1] ) b = array( [2,2,2] ) c = array( [3,3,3] ) d = array( [4,4,4] )
a = f(a) b = f(b) c = f(c) d = f(d)
I would like to replace :
a = f(a) b = f(b) c = f(c) d = f(d)
with something like that, but which really modify a,b,c and d:
for x in [a,b,c,d]: x = f(x)
So having something like a pointer on the arrays.
Thanks for your help !
