## usage: surf ([x, y,] z )
##
## Shaded Surface plot with magnitude coloring.
##
## If x, y, and z are matrices with the same dimensions,
## then corresponding elements represent vertices of the plot.
##
## If x and y are vectors, then a typical vertex is (x(j), y(i), z(i,j)).  Thus,
## columns of z correspond to different x values and rows of z correspond
## to different y values.
