Particle filter resampling

Author: Jose Luis Blanco

This MATLAB toolkit contains functions and scripts demonstrating four different approaches to resampling:
- Multinomial
- Residual
- Stratified
- Systematic (universal sampling).

The main entry points for this toolkit are:
- runAnalysis.m
- runExample.m

A C++ version of these algorithms are part of the MRPT library ( ).

Many thanks. I'm trying to understand this.

Lack of documentation and good comments. Many comments are in Spanish. The program is very particular to the system analyzed here. I have difficulties understanding this code.

I'm trying to understand this... you describe it as a SIS, yet i do not see any importance sampling taking place, as no new samples are drawn at each step (only during the resampling step). i had understood that SIS drew samples each step from an importance distribution - or perhaps i've got that wrong?
