SUBROUTINE  PLTSE (Z1,ZE,Z2,NX,MX,NY)

C     [SOUTHEAST VIEW]
C     PROGRAM TO PRODUCE A PERSPECTIVE DRAWING OF A SINGLE VALUED
C     FUNCTION DEFINED IN CARTESIAN COORDINATES, IN SUCH A WAY AS
C     TO EXHIBIT ARCS ON THE SURFACE PARALLEL TO THE COORDINATE
C     AXES. FOR GREATER CLARITY IN PRESENTATION, THE ENTIRE FIGURE
C     MAY BE SHEARED, HORIZONTALLY WHICH WILL GIVE THE ILLUSION OF
C     A SIDEWISE PERSPECTIVE, AND VERTICALLY TO GIVE THE ILLUSION OF
C     DEPTH AND TO EXPOSE THE REMOTER DETAILS WHICH WOULD OTHERWISE
C     BE HIDDEN.  SHEARING IS PREFERABLE TO ROTATION WHENEVER IT IS
C     DESIRED TO MAINTAIN HORIZONTAL LINES HORIZONTAL.
