Python | Numpy np.lagval() method (original) (raw)

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.]]
