I have T=81x4 struct, each member has two fields (x and y cordinate). I want to plot each row which will be 4 nodes to make a rectangular by connecting the nodes. Totally it should be 81 rectangular. I am wondering how can I plot each row of struct with 2 fields. I would appreciate if anyone can help me.
for i=1:81
plot(T(i,:).x,T(i,:).y,'.')
xlim([-50 50]);
ylim([-50 50]);
k = boundary(x,y);
hold on;
plot(x(k),y(k));
end

Try this
x=reshape([T(:).x],size(T));
y=reshape([T(:).y],size(T));
plot(x(:,[1:end 1])',y(:,[1:end 1])')
