Polynomial Equation Solver

Welcome to Equation Calculator. The Equation Calculator allows you setup equations, define and set Variable Values, and calculate an equation result. You can create a record with variables and values or a each equation. Equations and variable values can be changed and saved in the same or...

This 15-line matlab program solves the nonlinear reactiondiffusion equation, called Kolmogorov-Petrovskii-Piskunov(KPP) equation to generate patterns (ribbons and rings).The numerical method is simple and program is easy tounderstand, and it can be extended to simulatedmore complex systems. The...

Given mean anomaly and eccentricity of an orbit, eccentric anomaly can be calculated using Kepler's Equation. However, the equation is nonlinear, and an iterative technique must be used. This program uses a fixed-point iterative technique to output eccentric anomaly to a user defined tolerance,...
