       gpiv_sstrain - Calculates the shear strain from PIV data.


       gpiv_sstrain  [-d  N]  [-h  | --help] [--no_g ] [-p | --print] [-g | --g] [-v | --version]
       [filename] < stdin > stdout


       gpiv_sstrain calculates the shear strain from  PIV  data.  You  can  choose  from  several
       differential schemes: central differentiation, least squares and Richardson extrapolation.
       The output can be generated as ASCII data containing  four  columns  or  as  GNUPlot  Data
       format that allows one to view/print the data as contour plots.

       The  configuration  parameters  (containing  the POST key) may be overruled by the command
       line options, as explained below.


       -d N   Differential type to be  used:  central  difference  (N=0),  least  squares  (N=1),
              Richardson interpolation (N=2), circulation method (N=3)

       -h | --help
              On-line help

       -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  filename  is

       -g     Show contour plot of the output with gnuplot.

       --no_g Suppresses to show contour plot of the output with gnuplot.

       -v | --version
              Print version information on standard output, then exit successfully.

       filename Input PIV data file. Overrides stdin and stdout. The
              output will be written to filename.sstr.  Parameters are stored in filename.par and
              may be used for future use by including them in ./gpivrc.
