采用numpy快速将两个矩阵或数组合并成一个数组： import numpy as np 数组 a = [[1,2,3],[4,5,6]] b = [[1,1,1],[2,2,2]] 1、数组纵向合并 1) c = np.vstack((a,b)) c = array([[1, 2, 3], [4, 5, 6], [1, 1, 1], [2, 2, 2]] 2) c = np.r_[a,b] c = array([[1, 2, 3], [4, 5, 6], [1, 1, 1], [2, 2, 2]]) 2、数组横向合并 1)、 d = np.hstack((a,b)) d = array([[1, 2, 3, 1, 1, 1], [4, 5, 6, 2, 2, 2]]) 2)、 d = np.c_[a,b] d = array([[1, 2, 3, 1, 1, 1],
[4, 5, 6, 2, 2, 2]])
