Second Order Differential Equations

This function solves the linear fractional-order differential equations (FODE) with constant coefficients. The short memory principle has not neen used here, so the length of input signal is limited to few hundred samples. The parameters of the FODE (in its standard form) are the inputs of this...

The main goal of this demo is to show how you can improve your visualization and understanding of a dynamic system that has simple second order differential equations but complex to visualize due to switching between them. By using 3D animation, you can get a much better understanding of the...

Graphical user interface (GUI) is used to solve up to two ordinary differential equations (ODEs). Results can be plotted easily. Choose between MATLAB's ode45 (non-stiff solver) or ode15s (stiffer solver).This is primarily a teaching tool.
