Download Repository: ZIP Archive

How to install (and uninstall) SDETools:

1. Download and expand the SDETools-master.zip ZIP archive of the repository.
2. Move the resultant SDETools-master folder to the desired permanent location.
3. In Matlab, navigate to SDETools-master/SDETools/ and run sde_install. This adds the necessary files and folders to the Matlab search path. To uninstall SDETools, run sde_install('remove').
4. Minor edits and bug reports and fixes can be submitted by filing an issue or via email. To add new functionality or make propose major changes, please fork the repository. Any new features should be accompanied by some means of testing. Email or file an issue if you have any questions.
