Add cells into a square
显示 更早的评论
Hi,
I have the below square. How can I create a mesh of cells inside the square generated from equal subdivision on each edge?
This is how I plotted the square:
ex = [0 1 1 0];
ey = [0 0 1 1];
%visualise the polygon
pgon = polyshape(ex,ey);
figure;
plot(pgon,'EdgeColor','black','FaceColor','none','LineWidth',2)
xlabel('$x$','Interpreter','latex')
ylabel('$y$','Interpreter','latex')
set(gca,'TickLabelInterpreter','latex')
set(gca,'FontSize',12)
Thanks.

ex = [0 1 1 0];
ey = [0 0 1 1];
m = 5 ;
n = 5 ;
A = [min(ex) min(ey)] ;
B = [max(ex) max(ey)] ;
x = linspace(A(1),B(1),m) ;
y = linspace(A(2),B(2),n) ;
[X,Y] = meshgrid(x,y) ;
plot(X,Y,'k',X',Y','k') ;

ex = [0 1 1 0];
ey = [0 0 1 1];
pgon = scale(polyshape(ex,ey),1/4); %prototype
[I,J]=ndgrid((0:3)/4);
pgon=arrayfun(@(x,y)translate(pgon,x,y),I,J); %shifted copies
figure;
plot(pgon,'EdgeColor','black','FaceColor','none','LineWidth',2)
xlabel('$x$','Interpreter','latex')
ylabel('$y$','Interpreter','latex')
set(gca,'TickLabelInterpreter','latex')
set(gca,'FontSize',12)
axis equal
