Throughout the first course of Numerical Analysis at the RWTH Aachen University I tried some matrix decompositions in PHP and based on the Slim framework I developed a small demonstration website - this project.
The demonstration application can be found here. My personal blog can be found at http://davidstutz.de/.
The application is licensed under the GPL v3.
