   1 \section{The grid}

   3 The object \verb+grille+ allows you to obtain a solid plane.
   4 The key \texttt{[base=$x{min}$ ${x{max}}$ ${y{min}}$
   5 ${y{max}}$]} lets you specify the dimension of the grid. % $

  19 The key \texttt{[ngrid=$n_1$ $n_2$]} lets you specify
  20 fineness of the grid. If $n_2$ is not set up, it is considered that $n_2 =
  21 n_1$.
  22
  23 If $n_1$ is an integer, it represents the number of grid points along the
  24 $Ox$ axis. If it is a real, it represents the  step size along the
  25 $Ox$ axis. For example, the number \verb+1+ is an integer, the number \verb+1.+ is real (note the decimal point).
