Python | Numpy np.chebgrid3d() method
With the help of np.chebgrid3d() method, we can get the array of coefficients after evaluation the chebyshev series on cartesian product of x, y and z by using np.chebgrid3d() method.
Syntax :
np.chebgrid3d(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.chebgrid3d() method, we are able to get the array of coefficients by evaluating the chebyshev series on the cartesian product of x, y and z.
# import numpy import numpy as np import numpy.polynomial.chebyshev as cheb # using np.chebgrid3d() method gfg = cheb.chebgrid3d((2, 5), (1, 3), (5, 6, -3), (2, -4, 1)) print(gfg) |
Output :
[502. 596. -250.]
Example #2 :
# import numpy import numpy as np import numpy.polynomial.chebyshev as cheb # using np.chebgrid3d() method gfg = cheb.chebgrid3d((1, -3, 7), (-2, 4, -8), (3, -4, 1), (2, -4, 1, 5, 1)) print(gfg) |
Output :
[57913404. 97926342. 4230432.]
