The ODE toolbox is always included with the base version of Ecolego.
The ODE toolbox allows you to create and simulate compartment models in Ecolego. Both linear and non-linear systems of ordinary differential equations are supported.
This toolbox adds the following functionality to Ecolego:
-
-
The
transport sub-system which allows you to approximate partial differential equations in one dimension.
An extensive library of numerical
solvers.
-
The ODE toolbox feature powerful numerical solvers of ordinary differential equations. Both variable and fixed step size solvers are available, as well as solvers for stiff systems.
-
Supports both linear and non-linear transfers
Discrete transfers
Saturation limits
