With the help of np.chebfromroots() method, we can get the chebyshev series with the roots passed as parameter in np.chebfromroots() method.
Syntax :
np.chebfromroots(roots)
Return : Return the chebyshev series.
Example #1 :
In this example we can see that by using np.chebfromroots() method, we are able to get the chebyshev series that is generated by roots those are passed by parameter.
# import numpy import numpy as np import numpy.polynomial.chebyshev as cheb   # using np.chebfromroots() method gfg = cheb.chebfromroots((2, 4, 8, 1))   print(gfg) |
Output :
[9.9375e+01 -1.3125e+02 3.5500e+01 -3.7500e+00 1.2500e-01]
Example #2 :
# import numpy import numpy as np import numpy.polynomial.chebyshev as cheb   # using np.chebfromroots() method gfg = cheb.chebfromroots((-3, 4, -5, 1, 10))   print(gfg) |
Output :
[-5.19125e+02 4.52375e+02 8.00000e+01 -1.24375e+01 -8.75000e-01 6.25000e-02]
