contour3
Remarks If you do not specify LineSpec, colormap and caxis control the color.
2-316
If X or Y is irregularly spaced, contour3 calculates contours using a regularly
spaced contour grid, then transforms the data to X or Y.
Examples Plot the three-dimensional contour of a function and superimpose a surface
plot to enhance visualization of the function.
[X,Y] = meshgrid([-2:.25:2]);
Z = X.*exp(-X.^2-Y.^2);
