Federic Moisy created wonderful package, called PIVMAT http://www.fast.u-psud.fr/pivmat/ which is simpler than our GUI-based post-processing package, http://www.openpiv.net/openpiv-spatial-analysis-toolbox/
BUT, it’s in Matlab which we decided to abandon and move all our activity to Python. So we also try to translate the PIVMAT into PIVPy. Of course it won’t be one-to-one translation because Python is by far richer language and provides us with some basic programming things that Matlab cannot. We hope that our effort will be useful.
