Fortran 90 and 77 codes by W.H. Press and G.B. Rybicki, for fast inversion matrices of an exponential form arising from autocorrelation functions of Ornstein-Uhlenbeck processes.
Computational physics development environment written in Fortran 90. It provides an environment where the physics of real systems can be modeled, by discretizing a set of partial differential equations on a mesh and solving the resultant algebraic system.
