Convert a polynomial to a Chebyshev series.

Convert an array representing the coefficients of a polynomial (relative to the “standard” basis) ordered from lowest degree to highest, to an array of the coefficients of the equivalent Chebyshev series, ordered from lowest to highest degree.

Parameters:

pol (array_like) – 1-D array containing the polynomial coefficients

Returns:

c (ndarray) – 1-D array containing the coefficients of the equivalent Chebyshev series.
