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.

import numpy as np

from numpy.polynomial.laguerre import lagval

x = 2

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

gfg = lagval(x, c)

print (gfg)

Output :

-7.0

Example #2 :

import numpy as np

from numpy.polynomial.laguerre import lagval

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

c = np.array([ 3 , 1 ])

gfg = lagval(x, c)

print (gfg)

Output :

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