Python | Numpy np.lagval3d() method (original) (raw)

Last Updated : 23 Jan, 2020

With the help of **np.lagval3d()** method, we can get the 3-D laguerre series at point x by using np.lagval3d() method.

Syntax : np.lagval3d(x, y, z, c)
Return : Return the 3-D laguerre series at point x, y and z.

Example #1 :
In this example we can see that by using np.lagval3d() method, we are able to get the 3-D laguerre series at point x, y and z by using this method.

import numpy as np

from numpy.polynomial.laguerre import lagval3d

x = np.array([[ 1 , 2 ], [ 3 , 4 ]])

y = np.array([[ - 5 , - 10 ], [ - 15 , - 20 ]])

z = np.array([[ 1 , 2 ], [ 3 , 4 ]])

c = np.array([ 1 , 2 ])

gfg = lagval3d(x, y, z, c)

print (gfg)

Output :

[[13. 44.]
[43. 94.]]

Example #2 :

import numpy as np

from numpy.polynomial.laguerre import lagval3d

x, y, z = 1 , 2 , 3

c = np.array([ 1 , 2 ])

gfg = lagval3d(x, y, z, c)

print (gfg)

Output :

1.0
