The goal of numerical analysis is the design and analysis of methods and algorithms to give approximate but accurate solutions to problems with no analytical expression of its solution. On one hand, ...

Abstract: An algorithm for instantaneous estimation of sinusoidal signals basing on numerical differentiation is presented in this paper. With all parameters unknown, the signal is sampled at a fixed ...

ABSTRACT: The optimality conditions for macroeconomic problems with limited commitment often contain partial derivatives of the optimal value function, corresponding to the outside option. This paper ...

Abstract: An algorithm for harmonic estimation based on numerical differentiation and central Lagrange interpolation of multipoint is presented in this paper. The proposed algorithm is adaptive for ...

Mathematical approaches for numerically solving partial differential equations. The focus will be (a) iterative solution methods for linear and non-linear equations, (b) spatial discretization and ...
