Hello there,
is there any way to make inverse matrix to solve linear equation, or any other way of doing it?
Im new to programing and processing itself, but i would like to make a program to building statics, which involve a lot equation solving which might be an issue without the matrixes.
Thanks in advance

I just found this on internet :

- [https://forum.processing.org/two/discussion/2439/recommended-library-for-matrix-operations-in-processing](https://forum.processing.org/two/discussion/2439/recommended-library-for-matrix-operations-in-processing)
- [Found a Matrix library](https://discourse.processing.org/t/found-a-matrix-library/2910)
- [http://ejml.org/wiki/index.php?title=Main\_Page](http://ejml.org/wiki/index.php?title=Main_Page)
Hope it helps π

Thank you very much. Unfortunately 3 out of 4 web pages are closed (at less for the download link) but i will definetly check out the EJML

Itβs strange because all the pages are working for me.
Have a great day π

@Feltopi β if you want to do Processing sketches with matrices, I suggest using R mode for processing.
[https://processing-r.github.io/](https://processing-r.github.io/)
Matrix data structures and operations of all kinds are native to R Project, and if you are already familiar with R or familiar with any similar math package (S language, MATLAB etc) then it should be easy to pick up.
