Re: [SciPy-User] array creation

Nov. 12, 2015


      thank you for help


import itertools
import numpy as np

ncols = 3
start, stop, step = 0.0, 1.0, 0.2

iterable = np.arange(start, stop+step/2, step)
mixing_ratios = itertools.product(iterable, repeat=ncols)
mixing_ratios = [i for i in mixing_ratios if np.isclose(sum(i), 1.0)]

Hi,
is there a function foo(ncols, min, max, delta) in mumpy/scipy to create
an array such as
0    100    0
0    0    100
10    90    0
10    80    10
10    70    20
10    60    30
10    50    40
10    40    50
10    30    60
20    20    70
20    10    80
20    0    90
20    80    0
...    ...    ...
90    10    0
90    0    10
100    0    0
Any help or link is welcome
