BRAWLER Border Functions

These are generalized shape functions used throughout brawler to provide shapes used for value functions. These functions replicate BRAWLER v7.5 border.f

Border is a smooth step function transitioning at 0. The formula used for positive and negative arguments are designed to make border be continuous in first derivative at z=0. Also, border(z,z0) = 1-border(-z,z0).

Parameters
zbasic independent variable
z0width-defining parameter
Returns
ranges from 0 for z < z0 to 1 for z > z0
double BRAWLER::border (const double z, const double z0)
double BRAWLER::cauchy (const double z, const double z0)
double BRAWLER::reward (const double z, const double z0)
