Syntax
Description
pdemesh(p,e,t)
plots the mesh specified by the mesh data p
, e
, and t
.
h=pdemesh(p,e,t)
additionally returns handles to the plotted axes objects.
pdemesh(p,e,t,u)
plots PDE node or triangle data u
using a mesh plot. If u
is a column vector, node data is assumed. If u
is a row vector, triangle data is assumed. This command plots substantially faster than the pdesurf
command.
The geometry of the PDE problem is given by the mesh data p
, e
, and t
. For details on the mesh data representation, see initmesh
.
This command is just shorthand for the calls
If you want to have more control over your mesh plot, use pdeplot
instead of pdemesh
.
Examples
Plot the mesh for the geometry of the L-shaped membrane.
Now solve Poisson's equation -u = 1 over the geometry defined by the L-shaped membrane. Use Dirichlet boundary conditions u = 0 on
, and plot the result.
