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

 
 To see the result in Gnuplot (gp373w32.exe) :          
 
    * compile and  execute the xx.c file.     => To create a value for u.
    * open the a3d.plt file with Gnuplot.     => Gnuplot draw u and v.
    * Press Return  into  the Dos window.     => To create a new value for u.
    * Use the command  "load   'a3d.plt'"     => With the arrow keyboard.
