Hello,
I am working on a script. The graph below must be plotted for all the values of N (N varies between 1 and +ve number). Now what is happening is if I run the script, for every iteration of N, values are plotted on to a new graph.
Instead, it would be really helpful if someone can check the script and help me to plot all the curves on to a single graph. I have attached the script. (Below is the expectation of the graph to look like)
Thanks in advance for your time.

See if the hold function will do what you want.

Ran in:
I looked at your code, however I do not understand the part that you would need to change to get that result. I do not understand where you want to put that plot. It is straightforward to change a subplot series to a single call using hold.
Example —
x = linspace(0, 15);
y(1,:) = 10 - (x-5).^2;
y(2,:) = 15 - (x-7).^2;
figure
subplot(1,2,1)
plot(x, y(1,:))
grid
subplot(1,2,2)
plot(x, y(2,:))
grid
sgtitle('Using ''subplot''')
figure
plot(x, y(1,:))
hold on
plot(x, y(2,:))
hold off
grid
title('Using ''hold''')
.
