Installation

The source files should be unpacked into an empty directory with a command:

tar xvzf rfg1.tgz

or on any Unix machine a more general command would be:

gunzip rfg1.tgz -c | tar xvf -

Since RFG routines are supposed to be integrated into other programs, and example main program was written in Fortran, containing a simple test of the RFG routine. The program file is $rfgtest.f$. To compile this file together with other files source files into an executable one should issue the $make$ command, like this:

make

This will create the executable $rfgtest$. The purpose of the test is to run a $genspec$ function at the beginning and run the $genvec$ function repeatedly to generate random vector field. To test the executable issue the command:

./rfgtest

This will produce a long output of numbers. The first 10 lines may look like this:
