Programs/Subroutines
Numerically efficient implementation of the modified Broyden’s method: mod_broydenr.f
This program is written in Fortran77 and makes extensive use of the BLAS (Basic Linear Algebra Subroutines) Library. A matrix inversion routine from LAPACK (Linear Algebra PACKage) is also used.
