参数 :

data :类似数组的输入数据
dtype : 返回数组的数据类型

返回值 :

Interprets the input as a matrix

# Python Programming illustrating
# numpy.asmatrix
  
import numpy as geek
  
# array-like input
b = geek.matrix([[5, 6, 7], [4, 6]])
print("Via array-like input : \n", b, "\n")
  
c = geek.asmatrix(b)
b[0, 1] = 10
print("c matrix : \n", c)

输出 :

Via array-like input : 
 [[[5, 6, 7] [4, 6]]] 

c matrix : 
 [[[5, 6, 7] 10]]
