For N grid points, the order of Lagrange interpolation functions is (N-1)th-order polynomials, different from the Hermite interpolation functions. To solve the difficulty in applying the multiple boundary conditions by using the conventional DQM, various methods have been proposed [7] and will be...

The numerical experiments conducted on various functions demonstrate the superiority of this algorithm, and the two methods are proven to be efficient for accelerating the convergence without leading the particle to premature convergence. 展开 关键词: INTERPOLATION PARTICLE swarm optimization STOCHASTIC ...
Barycentric interpolation is not new, but most students, most mathematical scientists, and even many numerical analysts do not know about it. This simple and powerful idea deserves a place at the heart of introductory courses and textbooks in numerical analysis.1 As always with polynomial ...
