À propos de Coupled Differential Equations

Two coupled 1st order differential equations are solved and the results plotted.

Upcoming changes:

1) Add a 2nd order coupled differential equation solver

2) Export solution data to txt, or csv format.

---

This app uses the runge kutta 4 algorithm to solve to coupled differential equations of the first order. The results are plotted and can be pinch zoomed. The workflow is streamlined via a custom keyboard and toast messages that help the user towards plotting a solution quickly.

This app is intended for students of science and engineering to get a qualitative understanding of how a coupled 1st order differential system behaves. Future versions of this app will let the user export data, generalize to "N" differential equations and also solve equations of the second order.

What's new in the latest 1.5

- Ability to save plots now added with new "Save" button.
- Slight performance upgrade by using background thread to run numerical solver.
- Sleek, black themed keyboard added.
- More updates coming in the future.
