orthax.orthadd
- orthax.orthadd(c1, c2, rec)Source
Add one orthogonal series to another.
Returns the sum of two orthogonal series c1 + c2. The arguments are sequences of coefficients ordered from lowest order term to highest, i.e., [1,2,3] represents the series
P_0 + 2*P_1 + 3*P_2.- Parameters:
c1 (array_like) – 1-D arrays of orthogonal series coefficients ordered from low to high.
c2 (array_like) – 1-D arrays of orthogonal series coefficients ordered from low to high.
rec (AbstractRecurrenceRelation) – Recurrence relation for the family of orthogonal polynomials.
- Returns:
out (ndarray) – Array representing the orthogonal series of their sum.
