Import via from kronbinations import *

Description

kronbinations is used to remove nested loops, to perform multidimensional parameter sweeps and to generate arrays to store results of such sweeps.

Usage:

• Pass arbitrarily many arrays to the constructor kronbinations, to iterate over all combinations of the arrays elements.

k = kronbinations(array([1,2,3]), array(['a','b','c']), array([False,True,False]))

• If you need to store results of some computation in an array, you can construct these arrays via k.empty(), k.ones(), k.zeros(), , k.full(fill_value), k.randint(), k.rng_random(rng) (and pass the corresponding numpy arguments , eg. k.zeros(dtype=int)).
• Finally you can iterate over all combinations using:

for index, values, changed in k.kronprod(index=True, change=True, progress=True):
    # Demonstrating a few of the functions here
    if changed[0]:
        print('First value changed')
    x[index] = values[0]
