orthax.chebyshev.cheb2poly(c)Source 

Convert a Chebyshev series to a polynomial.

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

Parameters:: c (array_like) – 1-D array containing the Chebyshev series coefficients, ordered from lowest order term to highest.
Returns:: pol (ndarray) – 1-D array containing the coefficients of the equivalent polynomial (relative to the “standard” basis) ordered from lowest order term to highest.
