This solver assembles and solves the FEM for the 2D scalar Helmholtz equation, using P1 triangular elements. The assembly is fully vectorized for efficiency.
For tutoring, the script of a "pedagogic" naive assembly is also provided in comments.
The resolution is performed using the Matlab \ operator (here leads to LU factorization).
Five different geometries are provided using built-in Matlab tools, but the solver is also compatible with arbitrary geometries. In particular, external mesh files (for instance from GMSH) can be used, while satisfying the PET format.
