    53=== 1.1 Aim ===
    6 
    74  The package uvmat can be used with a wide variety of input data: all image and movie formats recognised by Matlab (see [section 3.1->#sec3.1]),  NetCDF binary files [#get_field get_field](see [section 7->#get_field]). It is however particularly designed for laboratory data obtained  from imaging systems: it includes a GUI to run the Particle Image Velocimetry  software [CIVx ->3], as well as tools for geometric calibration, masks, grid generation and image pre-processing (e.g. background removal), and editing xml documentation files. Stereoscopic PIV, PIV-LIF and 3D PIV in a volume (still under development) are handled.

    118  Installation is described in [Presentation and download ->4] with package available there in a static version. The latest version can be downloaded from a [svn server->http://servforge.legi.grenoble-inp.fr/projects/soft-uvmat].

    1511  The master piece is a Matlab GUI, made of a Matlab figure '''uvmat.fig''' and an associated set of sub-functions in the file {uvmat.m}. The menu bar at the top of the GUI, push buttons and editing box in  '''uvmat.fig''' activate the Matlab sub-functions (callback functions) in {uvmat.m}.  The package also contains the following set of GUI (see [overview of the package->#overview] for a complete list).

    266262  Each field is then a multi-dimensional array V whose dimensions match the space dimensions.  Because of the grid regularity, the set of positions is fully defined by the coordinate value for the first and last index along each dimension of the array.

    270266  Each field is again a multi-dimensional array V whose dimensions match the space dimensions, but the coordinates may not be regularly spaced, so they are represented as a monotonic 1D array variable with the same length as the corresponding dimension of V.  This is called a 'coordinate variable' (see section 7.1).
     
    554550  With a projection object with title PATCH, the global histogram of field variables on the selected region will be obtained.
    555551
    556 In the case of two input files series, the field difference will be perfomed like with the interface uvmat.fig. It is not possible to use more than two input series for this funtion.
