With the help of np.chebval3d()
method, we can get the array of coefficients after evaluation on (x, y, z) on chebyshev series by using np.chebval3d()
method.
Syntax : np.chebval3d(x, y, z, c)
Return : Return an array after evaluation on (x, y, z).
Example #1 :
In this example we can see that by using np.chebval3d()
method, we are able to get the array of coefficients by evaluating (x, y, z) on chebyshev series.
import numpy as np
import numpy.polynomial.chebyshev as cheb
gfg = cheb.chebval3d(( 2 , 5 ), ( 1 , 3 ), ( 4 , 8 ), ( 2 , - 4 , 1 ))
print (gfg)
|
Output :
[408. 784.]
Example #2 :
import numpy as np
import numpy.polynomial.chebyshev as cheb
gfg = cheb.chebval3d(( 1 , 3 , 5 , 7 ), ( 2 , 4 , 8 ), ( - 10 , - 12 ), ( 2 , - 4 , 1 , 5 , 1 ))
print (gfg)
|
Output :
[1.04493678e+10 1.50855857e+10]
