numpy生成随机矩阵

1.源码实现

import numpy as np;
import random as rd;

A = np.random.rand(3)
B = np.random.rand(3, 3)
C = np.random.rand(3, 3, 3)

print("A =", A)
print("B =", B)
print("C =", C)

2.运行及其结果

$ python3 random_1.py 
A = [ 0.31880091  0.24481087  0.09568605]
B = [[ 0.21711139  0.70239533  0.71976923]
 [ 0.8139679   0.49379826  0.19379585]
 [ 0.4712822   0.22926796  0.60298726]]
C = [[[ 0.65977639  0.88701896  0.19543756]
  [ 0.45021699  0.34486738  0.0119728 ]
  [ 0.63649554  0.15397883  0.50004449]]

 [[ 0.98309559  0.27648943  0.71336816]
  [ 0.04985408  0.4521457   0.36350213]
  [ 0.05329061  0.97884136  0.12995352]]

 [[ 0.9055198   0.00220075  0.50801991]
  [ 0.31568117  0.20633831  0.05842598]
  [ 0.55251133  0.48417473  0.57347605]]]
