How can I plot graph only specific coordinate values from a PDE solved using the FEM method?

2 views (last 30 days)
model = createpde(1);
R1 = [3,4,-2.5,2.5,2.5,-2.5,-0.5,-0.5,0.5,0.5]';
i made a pde mesh like this and solve problem by FED method.
but I want to plot a graph only the values of x=-2.5~2.5 when the y-coordinate is 0.
How can I extract it?
