Nonlinear Equations MT

The Nonlinear Equations MT applications module (NLSYS) solves systems of nonlinear equations where there are as many equations as unknowns. This application is thread-safe and takes advantage of structures found in later versions of GAUSS.

The functions must be continuous and differentiable. You may provide a function for calculating the Jacobian, if desired. Otherwise NLSYS will compute the Jacobian numerically. You can also select from two descent algorithms, the Newton method or the secant update method, and from two step-length methods, a quadratic/cubic method, or the hookstep method.

Platform: Windows, LINUX, Mac, and UNIX.

Requirements: GAUSS/GAUSS Engine/GAUSS Light version 6.0 or higher.
