Generate X and Y arrays for 3-d plots.

  This is an obsolete routine.  Use the new MESHGRID1Y7VXN8 instead.

  Note: The MESHGRID1Y7VXN8 with MATLAB Version 4.0 produces a Y which is

  flipud(Y) of the Y from MESHDOM.

  The usage remains the same and the mesh plots are the same if

  Version 4.0 has been set to axis('ij').



  [X,Y] = MESHDOM(x,y)  transforms the domain specified by vectors

  x and y into arrays X and Y that can be used for the evaluation

  of functions of two variables and 3-d mesh and surface plots.

  The rows of the output array X are copies of the vector x and

  the columns of the output array Y are copies of the vector y.



  For example, to evaluate and plot the function  x*exp(-x^2-y^2)

  over the range  -2 < x < 2, -2 < y < 2,



      [X,Y] = meshdom(-2:.2:2, -2:.2:2);

      Z = X .* exp(-X.^2 - Y.^2);
