With the help of numpy.random.rayleigh() method, we can get the random samples from Rayleigh distribution and return the random samples.

Rayleigh distribution function

Syntax : numpy.random.rayleigh(scale=1.0, size=None)

Return : Return the random samples as numpy array.

Example #1 :

In this example we can see that by using numpy.random.rayleigh() method, we are able to get the rayleigh distribution and return the random samples.

Python3




# import numpy
import numpy as np
import matplotlib.pyplot as plt
  
# Using rayleigh() method
gfg = np.random.rayleigh(3.4, 50000)
  
plt.figure()
plt.hist(gfg, bins = 50, density = True)
plt.show()


Output :

Example #2 :

Python3




# import numpy
import numpy as np
import matplotlib.pyplot as plt
  
# Using rayleigh() method
gfg = np.random.rayleigh(2 * np.sqrt(np.pi), 100000)
  
plt.figure()
plt.hist(gfg, bins = 50, density = True)
plt.show()


Output :
