AnyLogic: Does anyone know what "int approximationOrder" in the constructor of a table function stands for?

Question

I want to use the constructor of an AnyLogic TableFunction, but I do not know what int approximationOrder stands for. The constructor without it is labeled as deprecated. Can anyone help?

Answer 1

int approximationOrder: the order (1, 2, 3...) of the approximation polynomial if the INTERPOLATION_APPROXIMATION mode is selected

If you do not set your InterpolationType to INTERPOLATION_APPROXIMATION then it does not matter what you choose here.

For example:

TableFunction x = new TableFunction(
    new double[]{1,2,3,4,5},
    new double[]{1,2,1,2,2},
    TableFunction.InterpolationType.INTERPOLATION_LINEAR,
    1, //approximationOrder makes no impact as we will not be using it
    TableFunction.OUTOFRANGE_ERROR,
    999.0
);

It is this parameter you see when you select your interpolation to approximation

What version of AnyLogic are you using? The latest version has this documented
