4.4 Nonlinear Calculation 4.4.1 Nonlinear Primitives Scilab provides several facilities for nonlinear calculations. Numerical simulation of systems of differential equations is made by the ode primitive.
Many solvers are available, mostly from odepack , for solving stiff or non-stiff systems.
Implicit systems can be solved by dassl . See ode and dassrt commands. Minimizing non linear functions is done the optim function. Enter help optim for more a more detailed description.
