Python | Numpy np.chebgrid2d() method (original) (raw)

Last Updated : 11 Nov, 2019

With the help of **np.chebgrid2d()** method, we can get the array of coefficients after evaluation the chebyshev series on cartesian product of x and y by using np.chebgrid2d() method.

Syntax : np.chebgrid2d(x, y, c)
Return : Return an array after evaluation on (x, y).

Example #1 :
In this example we can see that by using np.chebgrid2d() method, we are able to get the array of coefficients by evaluating the chebyshev series on the cartesian product of x and y.

import numpy as np

import numpy.polynomial.chebyshev as cheb

gfg = cheb.chebgrid2d(( 2 , 5 ), ( 1 , 3 ), ( 2 , - 4 , 1 ))

print (gfg)

Output :

[32. 94.]

Example #2 :

import numpy as np

import numpy.polynomial.chebyshev as cheb

gfg = cheb.chebgrid2d(( 1 , 3 , 5 , 7 ), ( 2 , 4 , 8 ), ( 2 , - 4 , 1 , 5 , 1 ))

print (gfg)

Output :

[719680. 6486180. 52831708.]
