random.vonmisesvariate() function in Python

Last Updated : 26 May, 2020

random module is used to generate random numbers in Python. Not actually random, rather this is used to generate pseudo-random numbers. That implies that these randomly generated numbers can be determined.

random.vonmisesvariate()

vonmisesvariate() is an inbuilt method of the random module. It is used to return a random floating point number with von Mises distribution or circular normal distribution.

Syntax : random.vonmisesvariate(mu, kappa) Parameters : mu : mean angle, expressed in radians between 0 and 2*pi kappa : concentration parameter, greater than or equal to zero Returns : a random von Mises distribution floating number

Example 1:

Python3 1==

# import the random module
import random

# determining the values of the parameters
mu = 0
kappa = 4

# using the vonmisesvariate() method
print(random.vonmisesvariate(mu, kappa))

Output :

0.9429600175580171

Example 2: We can generate the number multiple times and plot a graph to observe the von Mises distribution.

Python3 1==

# import the required libraries 
import random 
import matplotlib.pyplot as plt 
  
# store the random numbers in a  
# list 
nums = [] 
mu = 0
kappa = 4
  
for i in range(100): 
    temp = random.vonmisesvariate(mu, kappa)
    nums.append(temp) 
      
# plotting a graph 
plt.plot(nums) 
plt.show()

Output :

Example 3: We can create a histogram to observe the density of the von Mises distribution.

Python3 1==

# import the required libraries 
import random 
import matplotlib.pyplot as plt 
  
# store the random numbers in a list 
nums = [] 
mu = 0
kappa = 4
  
for i in range(10000): 
    temp = random.vonmisesvariate(mu, kappa) 
    nums.append(temp) 
      
# plotting a graph 
plt.hist(nums, bins = 200) 
plt.show()
