Numerical solution of third order singular boundary value problems with nonclassical SE-sinc-collocation and nonclassical DE-sinc-collocation

Results in Applied Mathematics, 2023
In this paper, we use the nonclassical SE-sinc-collocation and nonclassical DE-sinc-collocation methods for the numerical solution of singular third-order boundary value problems. The novelty of the approach is based on using the new non-classical weight

Two Reliable Computational Techniques for Solving the MRLW Equation

Axioms, 2023
In this paper, a numerical solution of the modified regularized long wave (MRLW) equation is obtained using the Sinc-collocation method. This approach approximates the space dimension of the solution with a cardinal expansion of Sinc functions.

A sinc-collocation method for initial value problems [PDF]

Mathematics of Computation, 1997
Summary: A collocation procedure is developed for the initial value problem \(u'(t) = f(t,u(t))\), \(u(0) = 0\), using the globally defined sinc basis functions. It is shown that this sinc procedure converges to the solution at an exponential rate, i.e., \( \mathcal{ O} (M^{2} \exp(-\kappa \sqrt{M}))\) where \(\kappa > 0\) and \(2M\) basis functions ...
