Information

This model is used to approximate the equation

y = if x > 0 then y1 else y2;

by a smooth characteristic, so that the expression is continuous and differentiable:

y = smooth(1, if x > x_small then y1 else

if x < -x_small then y2 else f(y1, y2));

In the region -x_small < x < x_small a 2nd order polynomial is used for a smooth transition from y1 to y2.
