A sub-package for efficiently dealing with polynomials.
Within the documentation for this sub-package, a “finite power series,”
i.e., a polynomial (also referred to simply as a “series”) is represented
by a 1-D numpy array of the polynomial’s coefficients, ordered from lowest
order term to highest. For example, array([1,2,3]) represents
P_0 + 2*P_1 + 3*P_2, where P_n is the n-th order basis polynomial
applicable to the specific module in question, e.g.,
“wraps” the “standard” basis) or
chebyshev. For optimal performance,
all operations on polynomials, including evaluation at an argument, are
implemented as operations on the coefficients. Additional (module-specific)
information can be found in the docstring for the module of interest.
