This repo has a program for investigating the structure of stochastic matrices in Monte Carlo simulations, especially like that. This is used to prove that a non-trivial perturbation on the stochastic matrix in the Monte Carlo simulation of a type of spin systems does not affect its eigenvalue distribution.
The programs in this repo was also used to generate data in the Ref.1.
