四个numpy数组的组合

Question

我试图以以下方式将4个数组组合成一个

a = ([1,5,9])
b = ([2,6,10])
c = ([3,7,11])
d = ([4,8,12])
combination = [[1,2,3,4][5,6,7,8][9,10,11,12]]

任何帮助都将非常感激

Answer 1

import numpy as np
a = ([1,5,9])
b = ([2,6,10])
c = ([3,7,11])
d = ([4,8,12])
print (np.stack((a,b,c,d), axis=-1))

输出:

[[ 1  2  3  4]
[ 5  6  7  8]
[ 9 10 11 12]]
