Python如何在numpy中合并两个矩阵 [英] Python how to combine two matrices in numpy

问题描述

Python的新手，在numpy中挣扎，希望有人能帮助我，谢谢！

new to Python, struggling in numpy, hope someone can help me, thank you!

from numpy  import *   
A = matrix('1.0 2.0; 3.0 4.0')    
B = matrix('5.0 6.0')
C = matrix('1.0 2.0; 3.0 4.0; 5.0 6.0')
print "A=",A
print "B=",B
print "C=",C

结果:

A= [[ 1.  2.]
   [ 3.  4.]]
B= [[ 5.  6.]]
C= [[ 1.  2.]
   [ 3.  4.]
   [ 5.  6.]]

问题:如何像Matlab C=[A;B]中那样使用A和B生成C?

Question: how to use A and B to generate C, like in matlab C=[A;B]?

推荐答案

使用 :

>>> import numpy as np
>>> np.concatenate((A, B))
matrix([[ 1.,  2.],
        [ 3.,  4.],
        [ 5.,  6.]])
