numpy.column_stack()
函数用于将一维数组作为列堆叠到二维数组中,它采用一维数组序列并将它们堆叠为列以构成一个二维数组。二维阵列堆叠as-is,就像hstack
函数。
用法: numpy.column_stack(tup)
参数:
tup :[ndarrays的序列]包含要堆叠的数组的元组。数组必须具有相同的第一维。
Return :[堆叠的二维数组]输入数组的堆叠的二维数组。
代码1:
# Python program explaining
# column_stack() function
import numpy as geek
# input array
in_arr1 = geek.array(( 1, 2, 3 ))
print ("1st Input array:\n", in_arr1)
in_arr2 = geek.array(( 4, 5, 6 ))
print ("2nd Input array:\n", in_arr2)
# Stacking the two arrays
out_arr = geek.column_stack((in_arr1, in_arr2))
print ("Output stacked array:\n ", out_arr)
输出:
1st Input array: [1 2 3] 2nd Input array: [4 5 6] Output stacked array: [[1 4] [2 5] [3 6]]
代码2:
# Python program explaining
# column_stack() function
import numpy as geek
# input array
in_arr1 = geek.array([[ 1, 2, 3], [ -1, -2, -3]] )
print ("1st Input array:\n", in_arr1)
in_arr2 = geek.array([[ 4, 5, 6], [ -4, -5, -6]] )
print ("2nd Input array:\n", in_arr2)
# Stacking the two arrays
out_arr = geek.column_stack((in_arr1, in_arr2))
print ("Output stacked array:\n ", out_arr)
输出:
1st Input array: [[ 1 2 3] [-1 -2 -3]] 2nd Input array: [[ 4 5 6] [-4 -5 -6]] Output stacked array: [[ 1 2 3 4 5 6] [-1 -2 -3 -4 -5 -6]]
