Error control
In order to determine the method constant error, order and stability properties, only one component of Yn can be supervised (practically, the evolution of an n-dimensional vector, if the ODE problem is n-dimensional).

In EpODE, the user must specify the 'final' variable which will approximate the problem solution. The values of the selected variable will be stored in the computational process, and, after that, these values can be visualized. In order to represent correctly the solution as a function on the independent variable and to find the method order, the user must specify the increment in the independent variable from a displayed 'starting' variable to the selected 'final' variable.
