MATLAB: Plot 2 1×4 matrices

matrice

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.

You forgot to specify the x-coordinates in plot(). Try this

%% Plotting problem
figure
subplot(6,1,1)
%figure





plot(1:one_plot, X(1:one_plot))
set(gca, 'XTick', hour_sub1, 'XTickLabel', tick_label_1);
ylim([0.0, 3])
subplot(6,1,2)
%figure
plot(one_plot+1:2*one_plot, X(one_plot+1:2*one_plot))
set(gca, 'XTick', hour_sub2, 'XTickLabel', tick_label_2)
ylim([0.0, 3])
subplot(6,1,3)
%figure
plot(2*one_plot+1:3*one_plot, X(2*one_plot+1:3*one_plot))
set(gca, 'XTick', hour_sub3, 'XTickLabel', tick_label_3)
ylim([0.0, 3])
subplot(6,1,4)
%figure
plot(3*one_plot+1:4*one_plot, X(3*one_plot+1:4*one_plot))
set(gca, 'XTick', hour_sub4, 'XTickLabel', tick_label_4)
ylim([0.0, 3])
subplot(6,1,5)
%figure
plot(4*one_plot+1:5*one_plot, X(4*one_plot+1:5*one_plot))
set(gca, 'XTick', hour_sub5, 'XTickLabel', tick_label_5)
ylim([0.0, 3])
subplot(6,1,6)
%figure
plot(5*one_plot+1:size(X), X(5*one_plot+1:size(X)))
set(gca, 'XTick', hour_sub6, 'XTickLabel', tick_label_6)
ylim([0.0, 3])

y = [ 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5 1 2 3 4 5];
plot(x,y)
hold on 
scatter(x(7),y(7),'r')
hold off
