Hello,
I cannot find any banded matrix specific solver in Matlab.
Does anyone has a recomendation on how to do it in Matlab or do I have to go to Python/C++/fortran?
Thanks

Since you've tagged this question with "sparse", try just using the backslash operator. The flowchart on that documentation page indicates when it will use a banded solver. Alternately, call decomposition with the 'banded' option and use the backslash operator on the decomposition object.

What constraints are you trying to place on the solution?

positivity for half of the unknowns, none on the other half
