xmeshinfo
Purpose
xmeshinfo
Get extended mesh information.
Syntax
Description
out = xmeshinfo(fem,...);
out = xmeshinfo(xmesh,...);
The xmeshinfo function provides information about the numbering of elements,
nodes, and degrees of freedom (DOFs) in the extended mesh and in the matrices
returned by assemble and the solvers.
