# MAGCODE: framework of models for calculating magnetic fields and interactions | ||
|
||
Hello! | ||
This repository contains code originally written for my PhD for calculating the forces | ||
(and stiffnesses) between permanent magnets and arrays of magnets. | ||
|
||
The GitHub repository for this code is located at: <https://github.com/wspr/magcode> | ||
|
||
It has been originally written in Matlab and a little Mathematica, | ||
and I plan on adding translations into other programming languages as time permits. | ||
Contributions happily accepted. | ||
|
||
|
||
Philosophy | ||
---------- | ||
|
||
As time goes by, it becomes increasingly difficult to build on the work of our | ||
predecessors unless we build tools to abstract the ideas we invent in our research. | ||
This code marks my first attempt to freely share, in a useful way, the work of my PhD. | ||
|
||
|
||
Installation and information | ||
---------------------------- | ||
|
||
The `matlab/` subdirectory of this repository contains the source files. | ||
After cloning the Git repository, you can simply add the `matlab/` folder to your Matlab | ||
path in order to start using the code. | ||
|
||
The documentation `matlab/magcode-matlab.pdf` contains both a user's guide and the | ||
documented source code in a literate programming style. | ||
|
||
|
||
Examples and test suite | ||
----------------------- | ||
|
||
The `examples/` subdirectory contains a number of files to illustrate the use of the `magnetforces` code (and other related things). These files are: | ||
|
||
- `allag_torques.m` is an implementation of the theory of [Allag and Yonnet (2009)][1] for calculating the torques between cuboid magnets. | ||
- `magnetforces_example.m` contains a reproduction of the results of [Akoun and Yonnet (1984)][2] and of [Janssen et al. (2009)][3]. | ||
- `multipole_compare.m` is an unfinished comparison between different configurations of multipole arrays. | ||
- `multipole_example.m` is a reproduction of the multipole results shown by [Allag, Yonnet, and Latreche (2009)][4]. | ||

|
||
The source code contains a number of automated tests to ensure that future changes don't break existing functionality or start producing incorrect results. These are not included in the repository for clarity; extract them with `mtangle`. | ||
