fortran90-gnuplot-test

This is a simple test to generate a data file using Fortran 90 (with the GFortran compiler) and then represent the 3D data using Gnuplot.

The main program generates 3D data of the function

$$ f(x, y) = \sin x \cdot \sin y $$

then, using the commands from the file gnuplot_script.txt the generated data in datafile.dat can be plotted in Gnuplot.

The resulting plot is
