This repository contains two examples: InversePinnConstantCoef.mlx and InversePinnVariableCoef.mlx. Both examples are solvers for an inverse problem for the Poisson equation $−\nabla \cdot (c\nabla ...

Abstract: Constant-coefficient multipliers are used in many DSP cores. A new low-power constant multiplier, with detailed design procedure, is presented. A generator written in C++ is used to generate ...

Abstract: In this paper we consider the asymptotic behaviour of one‐leg Θ‐methods when applied to the pantograph equation y′(t) = a(t) y(t) + b(t) y(q t), t ≥ 0, y(0) = ȳ, where a(t) and b(t) are ...
