Linear Stability Analysis (LSA) for two-variable reaction-diffusion (RD) models

The script offers a quick and easy way to perform LSA on RD models and visualize the results, and comes with the convenience of having the data for further processing or analysis. In the example, the phase portrait and the dispersion curves are calculated for the Lengyel-Epstein model (a=11, b=0.28, s=50).

Matlab functions to import 2D and 3D FlexPDE output ASCII data

Visualizing and further processing the results of finite-element simulations are challenging sometimes. These scripts can be added to any Matlab code (tested for ver. 2010a) to import the output of FlexPDE's "table" command.

4th-order Runge-Kutta method for solving reaction-diffusion equations in 2D

This bit of C code is written mainly for students who would like to learn the basics of how reaction-diffusion problems can be solved numerically. It provides a good opportunity for the user to understand the steps of the process, and to solve problems of their interest by modifying it. (The code was developed using Dev-C++ and tested on Windows XP and 7)
