Integrating with Existing Code

Mathematical notation has evolved over centuries to efficiently communicate technical concepts such as the sparse graph Laplacian construction in the top left. Meanwhile, programming languages communicate with a machine typically with a reduced character set and syntax causing handwritten translation of mathematics to visually stray far from the “chalkboard math” and from each other.
I❤️LA is a novel domain specific language for linear algebra. The I❤️LA code written with rich Unicode symbols visually resembles chalkboard math, while still being a semantically well-defined programming language compilable to various target languages: LaTeX, MATLAB, Python, C++.
