Matlab - FEM: Meshing polygon

Question

I have problem with meshing this polygon:

I need fill this polygon with one of this finite element:

I don't how to type a code for this problem and then plot this polygon with mesh, all without using PDEtool.

Thank you.

Answer 1

I made sth like that:

matX = [0,0.2,0;
        0.2,0.2,0;
        0.2,1,0.2;
        1,1,0.2;
        0,0.2,0;
        0.2,0.2,0;
        0.2,1,0.2]

matY = [0,0,0.5;
        0,0.5,0.5;
        0,0,0.5;
        0,0.5,0.5;
        0.5,0.5,1;
        0.5,1,1;
        0.5,0.5,1]

x = zeros(7,4);
y = zeros(7,4);    

for i=1:7    
    x(i,:) = [matX(i,1),matX(i,2),matX(i,3),matX(i,1)];
    y(i,:) = [matY(i,1),matY(i,2),matY(i,3),matY(i,1)];
    plot(x(i,:),y(i,:))
    hold on
end

Mesh:

Have anyone better and more sophisticated solution?
