WebChebyshev approximation and its relation to polynomial interpolation at equidistant nodes has been discussed. We have illustrated how the Chebyshev methods approximate with … WebThe N=2 Chebyshev differentiation matrix turns out to be: In general, we observe: • Differentiation matrices from local finite difference approximants are sparse and banded • Differentiation matrices from global Chebyshev approximants are dense It is possible to write an efficient algorithm to evaluate both types of [D N] matrices. WebApr 13, 2024 · We compared the performance of the proposed scheme in terms of both approximation accuracy and computational cost, based on eight benchmark problems, three index-1 DAEs and five stiff problems of ODEs, thus comparing it with ode23t and ode15s adaptive step-size solvers of the MATLAB ODE suite. 4 4.
