On approximate inverse of Hermite and Laguerre collocation differentiation matrices and new collocation schemes in unbounded domains
In this paper, we provide an explicit, stable and fast means to compute the approximate inverse of Hermite/Laguerre collocation differentiation matrices, and also the approximate inverse of the Hermite/Laguerre collocation matrices of a second-order differential operator. The latter offers optimal p...
