Polynomial degree reduction in the L2-norm on a symmetric interval for the canonical basis
In this paper, we develop a direct formula for determining the coefficients in the canonical basis of the best polynomial of degree M that approximates a polynomial of degree N>Mon a symmetric interval for the L2-norm. We also formally prove that using the formula is more computationally efficien...
