Graphdrawer and Mathemathic Equation Evaluator of Expressions

By Ivo Skalický

Abstract

This work deals with utilization of precedence syntax analysis for conversion of mathematical expression into dynamic object model in order of evaluate and go on processing expressions. Objective was to create a program, which connects function of scientific calculator and graph drawer. Program can evaluate mathematical expressions in scope of real numbers, calculate fractional expressions, numerically integrate and analytically derive in accordance with a given parameter. Besides it provides function for depiction of any given curve explicitly, implicitly or parametricly into 2D graph. Graphic output can be exported in selectable resolution into several basic raster and vector formats. On account of portability Java was chosen as a language of implementation
