TI Nspire shortcuts for finding Markov chain stationary distribution

In previous installment, the stationary distribution of Markov chain is determined in TI Nspire using built-in linSolve function. Apart from the implementation used, there are some shortcuts in TI Nspire that will arrive the same result. The first one is kind of a one-liner that distill all steps for solving for the stationary distribution, which can easily be programmed in Nspire using TI-Basic, is exemplified below in self-explanatory notes:

The full one-liner in TI Nspire is as below:



The other one is based on the fact the stationary distribution converges itself after repeated multiplication. This is tedious before the advent of modern computation power, but a piece of cake today even with hand-held calculators 🙂
