Python | Numpy np.lagval() method

Last Updated : 23 Jan, 2020

With the help of np.lagval() method, we can get the laguerre series at point x by using np.lagval() method.

Syntax : np.lagval(x, c) Return : Return the laguerre series at point x.

Example #1 : In this example we can see that by using np.lagval() method, we are able to get the laguerre series at point x by using this method.

Python3 1=1

# import numpy and lagval
import numpy as np
from numpy.polynomial.laguerre import lagval

x = 2
c = np.array([3, 10])

# import np.lagval() method
gfg = lagval(x, c)

print(gfg)

Output :

-7.0

Example #2 :

Python3 1=1

# import numpy and lagval
import numpy as np
from numpy.polynomial.laguerre import lagval

x = np.array([[1, 5], [2, 10]])
c = np.array([3, 1])

# import np.lagval() method
gfg = lagval(x, c)

print(gfg)

Output :

[[ 3. -1.] [ 2. -6.]]
