ofxMarkovChain

Introduction

This is a simple openFrameworks addon for generating random states using a Markov chain. The transition matrix can be set programmatically or with a text file.

Usage

Create a transition matrix from a file:

ofxMC::Matrix mat("transitionMatrix.txt");

Setup the Markov chain with the loaded matrix, in state 0:

ofxMC::MarkovChain markov;
markov.setup(mat, 0);

Update the state of the Markov chain:

markov.update();

You can get the state of the Markov chain like this:

markov.getState();

It will return an int representing the state of the Markov chain, starting at 0.

You can draw the Markov chain with the draw() method.

Examples

The example example-rainfall depends on the ofxGui addon to work. The example example-random_walker has no dependency (except ofxMarkovChain of course).

Compatibility

This addon was tested with Linux and openFrameworks v0.8.3
