 Try the examples in this order. 

 (You can compile the *.c files directly without create a project)

 To see the result in Gnuplot (gp373w32.exe) :          

    * compile and execute the *.c file.     => To create a value for u.
    * open the file aa2d.plt with Gnuplot.  => Gnuplot draw u and v. 
    * Press Return in Dos Windows.          => To create a new value for u.
    * Use the command Replot in Gnuplot.    => To draw the news u and v.
