Jsurf

3D plot onto an arbitrary surface.

JSURF is similar in almost all respects to the standard SURF plot except that it admits a second matrix T of z-coordinates of size [m,n] that is used to plot over the base surface described by coordinates (x,y,z).

JSURF(x,y,z,T) plots the 3D surface T onto the surface described by (x,y,z). JSURF(x,y,z,-T) plots on the underside of the surface. The colour scale is determined by the range of T.

JSURF(...,'PropertyName','PropertyValue',...) sets the surface property values for the object.

h = JSURF(...) returns the handle to the plot object.

This plot function was developed under version 7 of Matlab and no guarantees can be given for versions lower than this.
