3-D Surface Plot with Contour
Display a matrix as a surface with contour plot below
Plotted Variables
Z) -- plot matrix values as heights above the x-y plane and map data values to colormap.
X,Y,Z) -- X and Y are vectors or matrices defining the x and y components of a surface.
X,Y,Z,C) - C is a matrix the same size as Z, defining surface color.
