Information

1. Purpose of model

Function is taken from the Buildings Library Version 2.10 (https://github.com/lbl-srg/modelica-buildings)

Function that approximates y=1 ⁄ x inside the interval -δ ≤ x ≤ δ. The approximation is twice continuously differentiable with a bounded derivative on the whole real line.

See the package Examples for the graph.
