With the help of numpy.random.laplace() method, we can get the random samples of Laplace or double exponential distribution having specific mean and scale value and returns the random samples by using this method.

laplace distribution

Syntax : numpy.random.laplace(loc=0.0, 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.laplace() method, we are able to get the random samples of laplace or double exponential distribution and return the random samples by using this method.



Python3




# import numpy 
import numpy as np
import matplotlib.pyplot as plt
  
# Using numpy.random.laplace() method
gfg = np.random.laplace(1.45, 15, 1000)
  
count, bins, ignored = plt.hist(gfg, 30, density = True)
plt.show()

Output :

Example #2 :

Python3




# import numpy 
import numpy as np
import matplotlib.pyplot as plt
  
# Using numpy.random.laplace() method
gfg = np.random.laplace(0.5, 12.45, 1000)
gfg1 = np.random.laplace(gfg, 12.45, 1000)
  
count, bins, ignored = plt.hist(gfg1, 40, density = True)
plt.show()

Output :
