4.14.5.35.1.1. ArctangentBackbone

hystereticBackbone('Arctangent', backboneTag, K1, gamma, alpha)

The backbone function \(F(x)\) is developed by Ranzo and Petrangeli (1998) and defined as

\[ \begin{align}\begin{aligned}F(x) = K_1atan(K_2x)\\K_2 = tan(\alpha)/\gamma\end{aligned}\end{align} \]

backboneTag (int)	integer tag identifying the backbone function.
K1 (float)	parameter \(K_1\).
gamma (float)	parameter \(\gamma\).
alpha (float)	parameter \(\alpha\).
