Plot 2 1x4 matrices

I'm trying to plot these two matricies: x = [1 4 4 1]; y = [1 1 4 4];

They're supposed to be coordinates to create this

I know it's probably a very simple solution, but whatever plot attempt I make, only a line shows up on the graph. Please let me know! Thank you

Here is one way:

x = [1 4 4 1];
y = [1 1 4 4];
figure
patch(x,y,'b')
set(gca,'XLim',[0 5],'YLim',[0 5])

That last line is only to show create a little space around the rectangle.

Thank you! I want to plot another box on the same figure. When I use patch(), it doesn't work. Any ideas?

it is another matrice

Please be more specific than "it doesn't work". Does it give an error message? Does it show something unexpected?

But, I'll make a guess here, that the second patch replaced the first one, which is the default behavior. You can use the hold command:

x  = [1 4 4 1];
y  = [1 1 4 4];
x2 = [1 3 3 1];
y2 = [1 1 3 3];
figure
hold on
patch(x,y,'b')
patch(x2,y2,'r')
set(gca,'XLim',[0 5],'YLim',[0 5])
