**Random Integer Vector** is a type of vector having a random integer value at each entry. Such types of vectors have a huge importance in Simulation and Machine Learning. **Random Integer Vector** can be defined by its *Upper Limit*, *Lower Limit*, and Length of the Vector (i.e. number of entries).

**随机整数向量**是在每个条目处具有随机整数值的向量类型。 这种类型的向量在仿真和机器学习中具有极其重要的意义。 **随机整数向量**可以通过其*上限* ， *下限*和向量的长度(即条目数)来定义。

In this article, we are going to create a random integer vector using inbuilt function numpy.random.randint().

在本文中，我们将使用内置函数numpy.random.randint()创建一个随机整数向量。

**Syntax:**

**句法：**

numpy.random.randint(low, up, length)
    
    low - lower limit for choosing random integer value
    up - upper limit for choosing random integer value
    length - Length of the desired vector

**Application:**

**应用：**

1.  Machine Learning
    
    机器学习
2.  Probability
    
    可能性
3.  Constraint Based Programming
    
    基于约束的编程
4.  Monte Carlo Simulation
    
    蒙特卡罗模拟

## 随机整数向量的Python程序 **(**Python program for random integer vector**)** ##

# Linear Algebra Learning Sequence
    # Random Integer Vector
    
    import numpy as np
    
    # Example 1, length 20
    t1 = np.random.randint(0,30,20)
    print('Example : ', t1)
    
    # Example 2, length 20
    t2 = np.random.randint(0,100,20)
    print('\n\nExample : ', t2)
    
    # Example 3, length 20
    t3 = np.random.randint(0,300,20)
    print('\n\nExample : ', t3)
    
    # Example 4, length 30
    t4 = np.random.randint(40,45,30)
    print('\n\nExample : ', t4)

**Output:**

**输出：**

Example :  [ 6  2 14 27 23 12 15  7 23 18 17 16 13 12 19  7 27 21 28 23]
    
    
    Example :  [65 41 80 12 12 91 10 77 31 66 29 98 11 40 41 52  7 18 80 26]
    
    
    Example :  [126  14 190  21 259 268 168  88 252 270 243 112 237 2  
    38 112 229 106 85  48]
    
    
    Example :  [44 40 42 40 42 42 44 43 43 42 41 42 42 44 42 41 41 40 
    40 42 43 40 42 40 44 44 40 43 40 40]
