euler {simecol} | R Documentation |
Solving initial value problems for
systems of first-order ordinary differential equations
(ODEs) using the simple Euler forward integration method.
A special version is available to work with odeModel
objects.

The solver method euler
is used to simulate ODE
models. It creates a local environment in a way that parameters,
inputs and equations are visible within the main function of the
odeModel
.
Normally, this function is called indirectly from sim
.
The Euler method is the most primitive integration method and can be regarded
simply as a fixed step solution of the corresponding difference equation.
A data frame of the model outputs (e.g. states) for all timesteps.
