Program to Solve initial value problems by various methods

initial value problem solver enter >>IVPsolve to start

Description

This programme is a spare-time project of Daniel Klawitter and Christian Jäkel, both students at the Dresden University of Technology. It is designed to solve initial value problems (IVP) of the form $y'=f(x,y)$ by various methods.
Just choose a method, an example, set the step size and press the start button. Additionally we implemented a step control at which the tolerance can be adjusted and the opted step size will be the initial step size.
After the numerical calculations are done, two graphics will occur. On your right hand side you can see the numerical solution of the IVP. On your left hand side, either the region of stability of the chosen method will be displayed, or if the step control is activated, the calculated step sizes will be shown. The other presented values are self-explanatory. Ones the graphics are plotted you can take a closer look at them by pressing the button with the Matlab symbol or the button below the left side window.
