explanation on boundary condition matrix
显示 更早的评论
where can i find an explanation about boundary condition matrix? especially what does each row in this matrix stands for. the documantation provided in the matlab help is not very clear.
thank you.

Have you looked at this page?
There is a general description of the matrix format along with two examples.
If you are defining boundary conditions in a MATLAB script, my own preference (and recommendation) is to write a "boundary file" (user-written MATLAB function) to define your boundary conditions instead of trying to create a boundary matrix. I find writing a boundary condition function to be much more straightforward than writing a boundary matrix. The approach is documented here:

The first argument to assempde (or pdenonlin, parabolic, etc) can be a function handle. For example:
b = @pdebound;
u=assempde(b, ...);
(Note, the function doesn't have to be named pdebound for this to work.)

When I have only Dirichlet boundary conditions, do I have to gibe "assempde" 4 matrixes (q,g,h,r) or just 2 matrixes (h,r) with the command
if true
b = @pdebund
u = assempde(b, ...)
end
