Convention
- Before starting working on something, check the "Pull requests" tab to see if there isn't anyone who's already doing the same thing!
- Convention: The sources' names will start with a capital letter: "Crout", "Doolittle", "Householder", "Givens" etc.
- Comment your sources!
- Test your sources with several input cases: eye matrix, full matrix, triu matrix, tril matric, random matrix, small, big etc.
- Use notation tags:
- [NOTE] for related notes
- [USES] for sources which use other sources that are in a different folder to suggest that the user should first copy the dependencies (sources needed) in the same folder for testing
- before creating a Pull Request, it should look like this: Householder
