gpiv_vhisto - Tests PIV data by printing/displaying an histogram of the vertical particle displacements.
gpiv_vhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout
Gpiv_vhisto calculates the histogram of the vertical particle displacement distribution between minimum and maximum values. The parameters read from the configuration resources (containing the key VALID) may be overruled by the command line options, as explained below.
-g Graphical visualization of the histogram with gnuplot. -h | --help On-line help -n N Override number of bins (default 10, hard coded). -p | --print Print parameters, command line options and eventually used input and output filenames to stdout. The output is identic of filename.par, in case -f is used. -v | --version Print version information on standard output, then exit successfully. filename Input PIV file. Overrides stdin and stdout. Output will be written to filename.pdf. The parameters will be written or appended to filename.par and may be used for future use by including them in ./gpivrc.
stdin and stdout has still to be implemented. [-f filename ] will be added.

The program seems to work fine with real PIV data. So far, no serious bugs have been found. 8 November 2006 GPIV_VHISTO(1)
