How to plot the five ellipses in the same figure?

Here is my code, where when xi_a takes a new value from xi for each iteration, the semi-axes of my ellipse changes.
Now my question is how to plot all the 5 ellipses in the same figure, as it will be easy for me to find by how much they differ from each other.
The two important lines in the coding is made bold ie., xi_a and figure(4)plot

Hi Priya,
‘. . . plot all the five ellipse generated in 5 iterations in one single figure.’
I don’t see where you get a and b. It must be over the horizon in a part of your code you didn’t post.
The idea in this code snippet here is to create vectors out of a and b as you go through your calculations in a loop, then create a second loop to do the plots.
This is what I would do:
for k1 = 1:5 % LOOP THAT GENERATES ‘a’, ‘b’
% . . . OTHER STATEMENTS IN YOUR CODE . . .
a(k1) = randi(5); % STATEMENT THAT CREATES ‘a’
b(k1) = randi(5); % STATEMENT THAT CREATES ‘b’
% . . . OTHER STATEMENTS IN YOUR CODE . . .
end
%===GENERATE THE ELLIPSE=======
xCenter = 0;
yCenter = 0;
xRadius = a;
yRadius = b;
theta = 0 : 0.01 : 2*pi;
for k1 = 1:length(a)
x = xRadius(k1) .* cos(theta) + xCenter;
y = yRadius(k1) .* sin(theta) + yCenter;
figure(4);
plot(x, y, 'LineWidth', 1)
axis square;
axis equal;
grid on;
xlabel('Longitudinal');ylabel('Lateral');title('Contact ellipse shape')
hold on
end
This plots five ellipses on the same axes using the vector elements of a and b.

Just don't call figure() all those times. In fact, don't call it at all. It will automatically create a figure with one axes, and all plots after you call "hold on" will be added onto the same axes control.
