Or, if you want the polynomials in some other representation - by values, or in terms of some basis of orthogonal polynomials - you can construct an appropriate Vandermonde-style matrix and use QR. (When I tried this, switching from the power basis to the Chebyshev basis let me go from tens to hundreds of polynomials, and now Chebyshev polynomials are first-class objects.)
