numpy.polynomial.chebyshev.chebadd#

polynomial.chebyshev.chebadd(c1, c2)[source]#

Add one Chebyshev series to another.

Returns the sum of two Chebyshev series c1 + c2. The arguments are sequences of coefficients ordered from lowest order term to highest, i.e., [1,2,3] represents the series T_0 + 2*T_1 + 3*T_2.

Parameters:
c1, c2array_like

1-D arrays of Chebyshev series coefficients ordered from low to high.

Returns:
outndarray

Array representing the Chebyshev series of their sum.
