This is Matlab code for the paper "Cusp Bifurcation under Additive Noise", where we consider the equation
  1. The script Cusp_asymptoticLE.m computes the asymptotic Lyapunov exponent.
  2. The script Cusp_single.m calculates the large deviation rate function for a single case.
  3. The script Cusp_all.m evaluates the large deviation rate function for a group of cases.
  4. The script Cusp_minimum.m determines the minimal large deviation rate.
In particular, the last three scripts will not run without Intlab, available at https://www.tuhh.de/ti3/rump/intlab/.
We also referenced the code implementation, available at: https://github.com/MaximeBreden/LDPforFTLE.
