D. Lutterkort et al., Polynomial degree reduction in the L-2-norm equals best Euclidean approximation of Bezier coefficients, COMP AID G, 16(7), 1999, pp. 607-612
Given a polynomial p of degree n we want to find a best L-2-approximation o
ver the unit interval from polynomials of degree m < n. This problem is sho
wn to be equivalent to the problem of finding the best Euclidean approximat
ion of the vector of Bernstein-Bezier coefficients of p from the vector of
degree-raised Bernstein-Bezier coefficients of polynomials of degree m. (C)
