Explicit differentiation matrices in various polynomial bases are presented in this work. The idea is to avoid any change of basis in the process of polynomial differentiation. This article concerns both degree-graded polynomial bases such as orthogonal bases, and non-degree-graded polynomial bases including the Lagrange and Bernstein bases.
In this paper, we have found explicit formulas for the differentiation matrix, D, in various polynomial bases. The most important advantage of having D explicitly is that there is no need to go from one basis to another (normally monomial) to differentiate a polynomial in a given basis. Moreover, having D, we can easily find higher order derivatives of any polynomial in its original basis. One may hope that new and more efficient polynomial-related algorithms, such as root-finding methods, can be developed using D.
These results can be easily extended to matrix polynomials in different bases.
