NAME

       gpiv_uhisto - Tests PIV data by printing/displaying an histogram of the horizontal particle displacements.

SYNOPSIS

       gpiv_uhisto [-g] [-h | --help] [-n N] [-p | --print] [-v | --version] [filename] < stdin > stdout

DESCRIPTION

       Gpiv_uhisto calculates the histogram of the horizontal 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.

Options
       -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  file-
	      name.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.

NOTES

       stdin and stdout has still to be implemented.  [-f filename ] will be added.

BUGS

       The program seems to work fine with real PIV data.  So far, no serious bugs have been found.
