set the appearance of zone edges in a filled mesh plot (plf or plfp).
By default, edges=0, and the zone edges are not plotted. If
edges=1, a solid line is drawn around each zone after it is
filled; the edge color and width are given by ecolor and ewidth,
which are "fg" and 1.0 by default.

writes the picture in the current graphics window to the Encapsulated
PostScript file NAME+".epsi" (i.e.- the suffix .epsi is added to NAME).
The eps function requires the ps2epsi utility which comes with the
project GNU Ghostscript program. Any hardcopy file associated with
the current window is first closed, but the default hardcopy file is
unaffected. As a side effect, legends are turned off and color table
dumping is turned on for the current window.
The external variable PS2EPSI_FORMAT contains the format for the
command to start the ps2epsi program.
