Extract the graph nodes' coordinates from a graphic window when N moving nodes are defined after Nf fixed nodes (MANET).
[Nx,Ny] = NL_F_XYExtraction(F,N,Nf)
Graphic window ID.
Quantity of moving nodes.
Quantity of fixed nodes.
X-coordinates.
Y-coordinates.
NL_F_XYExtraction extracts the graph nodes' coordinates from the graphic window defined by its handle F when N moving nodes are defined after
fixed nodes.
