SYNOPSIS  
   plot3dcl ( x ,  y ,  z ,  nx ,
     ny ,  opt ,  clevel ,  nlevel ,  indexxmin ,
     indexxmax ,  indexymin ,  indexymax ) 
 
  DESCRIPTION  
  When the implementation is completed this variant of
      plot3dc (3plplot)  (see that function's documentation for more details)
    should be suitable for the case where the area of the  x ,  y 
    coordinate grid where  z  is defined can be non-rectangular. The
    implementation is incomplete so the last 4 parameters of plot3dcl;
     indexxmin ,  indexxmax ,  indexymin , and  indexymax ;
    are currently ignored and the functionality is otherwise identical to that
    of   plot3dc (3plplot) . 
 Redacted form: General:  plot3dcl(x, y, z, opt, clevel,
    indexxmin, indexymin, indexymax)   
  
 This function is not used in any example. 
 
  ARGUMENTS  
  
     x 
    ( PLFLT_VECTOR (3plplot), input)  
   A vector containing the x coordinates at which the function is
    evaluated. 
     y 
    ( PLFLT_VECTOR (3plplot), input)  
   A vector containing the y coordinates at which the function is
    evaluated. 
     z 
    ( PLFLT_MATRIX (3plplot), input)  
   A matrix containing function values to plot. Should have dimensions of
       nx  by  ny . 
     nx  ( PLINT (3plplot),
    input)  
   Number of  x  values at which the function is evaluated. 
     ny  ( PLINT (3plplot),
    input)  
   Number of  y  values at which the function is evaluated. 
     opt 
    ( PLINT (3plplot), input)  
   Determines the way in which the surface is represented. To specify more
      than one option just add the options, e.g. DRAW_LINEXY + MAG_COLOR
       opt =DRAW_LINEX : Lines are drawn showing  z  as a function of
       x  for each value of  y [j] .  opt =DRAW_LINEY : Lines are
      drawn showing  z  as a function of  y  for each value of
       x [i] .  opt =DRAW_LINEXY : Network of lines is drawn
      connecting points at which function is defined.  opt =MAG_COLOR :
      Each line in the mesh is colored according to the z value being plotted.
      The color is used from the current cmap1.  opt =BASE_CONT : A contour
      plot is drawn at the base XY plane using parameters  nlevel  and
       clevel .  opt =DRAW_SIDES : draws a curtain between the base XY
      plane and the borders of the plotted function.
      
   
     clevel 
    ( PLFLT_VECTOR (3plplot), input)  
   A vector containing the contour levels. 
     nlevel 
    ( PLINT (3plplot), input)  
   Number of elements in the clevel vector. 
     indexxmin 
    ( PLINT (3plplot), input)  
   The index value (which must be ≥ 0) that corresponds to the first
       x  index where  z  is defined. 
     indexxmax 
    ( PLINT (3plplot), input)  
   The index value (which must be ≤  nx ) which corresponds (by
      convention) to one more than the last  x  index value where  z 
      is defined. 
     indexymin 
    ( PLINT_VECTOR (3plplot), input)  
   A vector containing  y  index values which all must be ≥ 0.
      These values are the first  y  index where  z  is defined for a
      particular  x  index in the range from  indexxmin  to
       indexxmax - 1 . The dimension of  indexymin  is
       indexxmax . 
     indexymax 
    ( PLINT_VECTOR (3plplot), input)  
   A vector containing  y  index values which all must be ≤
       ny . These values correspond (by convention) to one more than the
      last  y  index where  z  is defined for a particular  x 
      index in the range from  indexxmin  to  indexxmax - 1 . The
      dimension of  indexymax  is  indexxmax .
