EASY-FIT ModelDesign 5.13 Klaus Schittkowski 

Education \ Science

The system solves constrained nonlinear parameter estimation (nonlinear regression, data, curve and surface fitting) problems based on ODEs, DAEs, PDEs, PDAEs, steady-state systems, Laplace equations, and analytical functions. A statistical analysis provides confidence intervals, correlation and covariance matrix, identification of significant. Free download of EASY-FIT ModelDesign 5.13, size 72.72 Mb.


   
 

EASY-OPT Express 2.0 Klaus Schittkowski 

Education \ Mathmatics

The software system allows to solve constrained nonlinear programming problems by an efficient sequential quadratic programming (SQP) method. A nonlinear objective function is to be minimized subject to nonlinear equality or inequality constraints. The mathematical method represents the scientific state-of-the-art. Model functions are defined. Freeware download of EASY-OPT Express 2.0, size 61.71 Mb.
