clc; close all; clear all;
x=[0 1 2 3 6 4 5 8 5];y=[9 8 5 6 3 2 1 5 2];
subplot(4,4,1); plot(x,y);subplot(4,4,2); plot(x,y);subplot(4,4,3); plot(x,y);
subplot(4,4,4); plot(x,y);subplot(4,4,5); plot(x,y);subplot(4,4,6); plot(x,y);
subplot(4,4,7); plot(x,y);subplot(4,4,8); plot(x,y);subplot(4,4,9); plot(x,y);
subplot(4,4,10); plot(x,y);subplot(4,4,11); plot(x,y);subplot(4,4,12); plot(x,y);
subplot(4,4,13); plot(x,y);subplot(4,4,14); plot(x,y);subplot(4,4,15); plot(x,y);subplot(4,4,16); plot(x,y);
How to put partitioning as shown in the image and write title for each category ?

Hi Reji,
clc; close all; clear all;
x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];
figure; % Create a new figure
for i = 1:16
subplot(4, 4, i); % Create each subplot
plot(x, y);
% Add title to each subplot
title(sprintf('Subplot %d', i));
if mod(i, 4) ~= 1
ax = gca;
ax.YAxis.Visible = 'off';
end
if i <= 12
ax.XAxis.Visible = 'off';
end
end
In this modified code, I've added a loop to create each subplot using subplot(4, 4, i), where i corresponds to the index of the subplot. Then, I plot the data in each subplot using plot(x, y).
To add titles to each subplot, I've used the title function with a formatted string sprintf('Subplot %d', i), where i represents the index of the subplot.
I've also adjusted the subplot spacing by hiding the y-axis labels for subplots that are not on the leftmost column (if mod(i, 4) ~= 1) and hiding the x-axis labels for subplots below the last row (if i <= 12).

Thank you. But I need partitioning lines to be visible. (Please see the red dashed line in my drawing)

If you want partioning using subplot titles then below is one method
clc; close all; clear all;
x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];
figure; % Create a new figure
k = 1;
for I = 1:16
subplot(4, 4, I); % Create each subplot
plot(x, y);
if I <= (4)
% Add title to each subplot
title(sprintf('Cat %d', k));
k = k+1;
elseif I > 4 & I <=8
title('')
elseif I > 8 & I <=12
title(sprintf('Cat %d', k));
k = k+1;
else
title('')
end
end
otherwise, you can also add space between the subplots using Position property of subplot

Hi Reji,
Please do it like the following:
I know the partition lines are encroaching over the subplots : ), but I thought you yourself would be better able to adjust them according to your requirements.
clc; close all; clear all;
x = [0 1 2 3 6 4 5 8 5];
y = [9 8 5 6 3 2 1 5 2];
figure; % Create a new figure
for i = 1:16
subplot(4, 4, i); % Create each subplot
plot(x, y);
% Add title to each subplot
title(sprintf('Cat %d', i)); % Change "Subplot" to "Cat"
if mod(i, 4) ~= 1
ax = gca;
ax.YAxis.Visible = 'off';
end
if i <= 12
ax.XAxis.Visible = 'off';
end
if i > 4
ax = gca;
hold on;
line([min(x)-0.5, min(x)-0.5], ylim, 'Color', 'r', 'LineStyle', '--', 'LineWidth', 1.5);
hold off;
end
if i <= 12 && mod(i, 4) ~= 0
ax = gca;
hold on;
line(xlim, [min(y)-2, min(y)-2], 'Color', 'r', 'LineStyle', '--', 'LineWidth', 1.5);
hold off;
end
end

Thank yoy for your time. I tried with the help of existing responses. But I couldn't adjust as like my hand sketch. That's why I posted it here. My requirement is well drawn in the sketch.
I need partition lines without break. Your red line is breaking at the end of a subplot.
