get solution in spesific point in the domain after solving pde

hi, after solving pde on some domain i've created using: u=assempde(b,p,e,t,c,a,f)

is it possible to extract the value in a spesific point in that domain?

thank you.

There are several ways to do this. Here is one simple one:

% p is the point matrix from initmesh 
% u is the solution from, e.g. assempde
F = TriScatteredInterp(p(1,:)', p(2,:)', u);
x = .5; y = .8; % location of a point in the model
upt = F(x,y);
