The OceanEddiesToolbox repository provides complementry scripts and functions to the Faghmous et al. 2015 eddy tracking software. All the scripts and functions were developed during my PhD Thesis work. The thesis Appendix E contains a tutorial for interested readers.
This toolbox will be beneficial for researcher seeking to promplty generate an eddy census for a specific study region. I have commented as much as I can to guide the students.

I acknowledge the developer of OceanEddies Toolbox for providing a well documented eddy tracking software. I learned a lot from the original code and tried my best to code in the similar style as the original software.
