numpy.polynomial.chebyshev. chebline(off, scl)[source]

Chebyshev series whose graph is a straight line.

Parameters: off, scl : scalars The specified line is given by off + scl*x.
Returns: y : ndarray This module’s representation of the Chebyshev series foroff + scl*x.

Examples

import numpy.polynomial.chebyshev as C C.chebline(3,2) array([3, 2]) C.chebval(-3, C.chebline(3,2)) # should be -3 -3.0
