      A more powerful form of plmesh
x
          (PLFLT_VECTORA vector containing the x coordinates at which the function is evaluated.
y
          (PLFLT_VECTORA vector containing the y coordinates at which the function is evaluated.
z
          (PLFLT_MATRIX
	    A matrix containing function values to plot.  Should have
	    dimensions of nx by ny.
          
nx
          (PLINT
            Number of x
ny
          (PLINT
            Number of y
opt
          (PLINTDetermines the way in which the surface is represented. To specify more than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR
                  
                    : Lines
                  are drawn showing
                  opt=DRAW_LINEX
                  
                     as a function
                  of z
                  
                     for each
                  value of x
                  
                    .

                    : Lines
                  are drawn showing
                  opt=DRAW_LINEY
                  
                     as a function
                  of z
                  
                     for each
                  value of y
                  
                    .
                x[i]
                  
                  
                    : Network
                  of lines is drawn connecting points at which function is
                  defined.
                opt=DRAW_LINEXY
                  
                  
                    : Each line
                  in the mesh is colored according to the z value being plotted. The
                  color is used from the current cmap1.
                opt=MAG_COLOR
                  
                  
                    : A contour
                  plot is drawn at the base XY plane using parameters
                  opt=BASE_CONT
                  nlevel and clevel.
                
                  
                    : draws a curtain
                  between the base XY plane and the borders of the plotted function.
                opt=DRAW_SIDES
                  
clevel
          (PLFLT_VECTORA vector containing the contour levels.
nlevel
          (PLINT
            Number of elements in the clevel vector.
          
      Redacted form: plmeshc(x, y, z, opt, clevel)
    
This function is used in example 11.
