What Davidson diagonalization in Fortran can do for you
- Follows modern Fortran practices
- Allows both dense and matrix-free calculations.
- Implements different correction methods
The Davidson method is suitable for diagonal-dominant symmetric matrices, that are quite common
in certain scientific problems like electronic structure. The Davidson method could be not practical
for other kinds of symmetric matrices.
