The Graphical User Interface of DIFFPAR

Abstract

Estimation of unknown parameters from measurements of a process modeled by a system of ordinary differential equations is an important application problem found in, e.g. control theory and chemical kinetics. The purpose of this paper is to present and describe a Matlab toolbox, called DIFFPAR (DIFF erential equations with unknown PARameters), which consists of a collection of Matlab functions that can be combined to perform different types of tasks: simulation, generation of data, sensitivity analysis, parameter estimation from data (real or generated) and statistical analysis of the parameters, etc. Keywords : parameter estimation, ODE-systems, Matlab toolbox 2 Graphical User Interface of DIFFPAR Contents 1 Introduction 4 2 The design of the GUI 4 3 How to use the GUI 7 4 Concluding remarks 8 5 References 8 A Push buttons and corresponding sub windows 9 A.1 GRAPH . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 11 A.2 SAVE . . . . . . . . . . . . . . . . . . . ...
