Shorthand command for surface plot
Syntax
Description
pdesurf(p,t,u)
plots a 3-D surface of PDE node or triangle data. If u is a column vector, node data is assumed, and continuous style and interpolated shading are used. If u is a row vector, triangle data is assumed, and discontinuous style and flat shading are used.
h=pdesurf(p,t,u)
additionally returns handles to the drawn axes objects.
For node data, this command is just shorthand for the call
pdeplot(p,[],t,'xydata',u,'xystyle','flat',... 'zdata',u,'zstyle','discontinuous','colorbar','off');
If you want to have more control over your surface plot, use pdeplot instead of pdesurf.
Examples
Surface plot of the solution to the equation -
u = 1 over the geometry defined by the L-shaped membrane. Use Dirichlet boundary conditions u = 0 on 
.
[p,e,t]=initmesh('lshapeg'); [p,e,t]=refinemesh('lshapeg',p,e,t); u=assempde('lshapeb',p,e,t,1,0,1); pdesurf(p,t,u)
