Home page of the Cephes Mathematical Library. - Resources: Acoustics, Laplace and Helmholtz Problems. Book, manuals, Fortran software (Free and to purchase). - A standard fortran 77 package for solving large-scale nonlinearly constrained optimization problems. Free download by FTP. - Ready to use solutions for optimization problems, or at least a way to build such a solution using work done by others. Where possible, public domain software is listed. - Used to identify parameters in explicit model functions, dynamic systems of equations (steady-state), Laplace transforms, ordinary differential equations, differential algebraic equations and one-dimensional partial differential equations. Proceeding from given experimental data. For example, observation times and measurements, the minimum least squares distances of measured data from a fitting criterion are computed, that may depend on the solution of the dynamic system. - Free general PDE solver driven by a user friendly language. Both a 2D and a 3D version are available. MacOS, Windows. - Software for high-performance computers available in source form for problems in numerical linear algebra, specifically dense, sparse direct and iterative systems and sparse iterative eigenvalue problems. - Free numerical analysis and visualization environment similar to Matlab. - Central location for custom scripts, functions and extensions to GNU Octave. - HSL (formerly the Harwell Subroutine Library) is a collection of ISO Fortran codes for large scale scientific computation, written by members of the Numerical Analysis Group and other experts.
