Polynomials *********** The polynomial package is newer and more complete than poly1d and the convenience classes are better behaved in the numpy environment. When backwards compatibility is not an issue it should be the package of choice. Note that the various routines in the polynomial package all deal with series whose coefficients go from degree zero upward, which is the reverse of the poly1d convention. The easy way to remember this is that indexes correspond to degree, i.e., coef[i] is the coefficient of the term of degree i. .. toctree:: :maxdepth: 2 routines.polynomials.poly1d .. toctree:: :maxdepth: 2 routines.polynomials.package
