Python讲堂 使用np.c_和np.r_实现数组转换成矩阵

https://www.cnblogs.com/yszd/p/9247242.html

import numpy as np
a = np.array([[1,2,3],[11,22,33]])
b = np.array([[4,5,6],[44,55,66]])
# 数组连接成矩阵
c = np.c_[a,b]
r = np.r_[a,b]
print('-------------按行转换成矩阵-----------------')
print(c)
print('-------------按列转换成矩阵-----------------')
print(r)
