The Homework Compiler comprises two programs: the Test Case Compiler and the Homework Compiler. Both are detailed below, but you can also look at their individual READMEs and wiki pages.
MATLAB R2018 or higher is strongly recommended. Versions of R2017 have seen apparent success, but insufficient testing has been done to ensure complete functionality.
Run build.m in the Test Case Compiler directory. Once it finishes, double-click the resulting .mlappintall file to install the Test Case Compiler as a MATLAB app. It should then show up in the apps list and be runnable from there.
Run build.m in the Homework Compiler directory. Double-click the resulting .mlappinstall file and run from the app toolbar.
See the Test Case Compiler wiki entry and the Homework Compiler wiki entry for instructions.
