Vortex Tracking Demonstration - Using Gamma 1 peak

This is a demonstration of the vortex core tracking algorithm proposed by Graftieaux et. al. (2001) in "Combining PIV, POD and vortex identification algorithms for the study o funsteady turbulent swirling flows".

The Matlab code and a small PDF write-up of the math I did to make this code fast (so i can use in high speed PIV data) can be found in the links below:
