MEDEA: Matrix Exponential Differential Equation Algorithm
Algorithm for the numerical integration of systems of ordinary differential equations arising in chemical problems. C ocde, free to use.
http://www.caspur.it/~castri/MEDEA/index.h...
Easy-Fit
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.
