This repo contains LAPACK-based T-Matrix codes originally written by M. Mishchenko.
ampld.lp.f, ampld.par.f and lpd.f are used for nonspherical particles in a fixed orientation. Here, ampld.lp.f is modified by Jussi Leinonen (jsleinonen@gmail.com) for his Python package pytmatrix.
tmd.lp.f, tmd.par.f and lpd.f are used for randomly oriented nonspherical particles.
Note that both are double-precision versions. The extended-precision versions are not included.
