PLOTM

Plot mapping values, contours or surface

    H = PLOTM(W,S,N)

Input
W	Trained mapping
S	Plot strings, or scalar selecting type of plot
1:	density plot;
2:	contour plot (default);
3:	3D surface plot;
4:	3D surface plot above 2D contour plot;
5;	3D mesh plot;
6:	3D mesh plot above 2D contour plot)
N	Contour level(s) to plot  (default: 10 contours between minimum and maximum)

Output
H	Array of graphics handles

Description

This routine, similar to PLOTC, plots contours (not just decision  boundaries) of the mapping W on predefined axis, typically generated by  SCATTERD. Plotstrings may be set in S. The vector N selects the contour.

If N = 'perc' 10 contour levels are drawn such that each level has an  equal area in the plot.
