--- UVMAT ---

UVMAT is a set of Matlab functions and graphic user interfaces for Particle Imaging Velocimetry with tools for scanning images and data files (vectors and scalars in 2D and 3D), geometric calibrations, image pre-processing and analysis of time series. It is designed to favor data management, relying on the standard NetCDF file format and xml documentation files.

This free Matlab toolbox (GNU licence) contains a PIV program under Matlab and a graphic user interface to run other programs, like the Correlation Image Velocimetry software CivX. Tools are provided to run programs on a computer cluster with different file administration systems (sge or oar).

This free Matlab toolbox contains a graphic user interface to scan and visualize series of images and data fields (vectors and scalars). It provides statistics and various processing for these data. It also contains a graphic user interface to run the Correlation Image Velocimetry software CIVx and analyze its results.


This toolbox requires Matlab, release R 2009 or more recent. It can be run with any computer system on which Matlab is installed (in particular Linux, MacOSX and Windows). No additional toolbox from Matlab is requested. The Matlab compiler is however useful to dispatch processing functions on a computer cluster.
