Numerical Caseology by Lagrange Interpolation for the 1D Neutron Transport Equation in a Slab

Here, we are concerned with a new, highly precise, numerical solution to the one-dimensional neutron transport equation based on Case’s analytical, singular eigenfunction expansion (SEE). While considerable number of solutions currently exist, understandably, because its complexity even in one dimension, there only few truly analytical equation. In 1960, Case introduced consistent theory SEE for variety idealized problems and forever changed landscape theory. Several methods, including Fn method, were What is presented yet another, called Lagrange order N method (LNM) featuring simplicity precision but more convenient natural Lagrangian polynomial basis.
