Hi everyone,
As per my script i expect an oputput of three plots but I get only one plot.
May someone suggets how i can fix this.
As per code there shoudl be three plots for t=1, 2 and 3, but i get only one plot for t=3.
clear all
clc
xs=8;
v=3;
L=20;
ta=0.2;
t=1:1:3;
for k=1:length(t)
n=1:1:40;
x=0:0.1:20;
omga = zeros(1,length(n));
F = zeros(1,length(n));
u = zeros(length(n),length(x));
for j=1:length(n)
F(j)=exp(-((n(j)*pi*v*ta/L).^2)/4);
u(j,:)=sin(n(j)*pi*xs/L)*F(j)*sin(n(j)*pi*x/L)*cos(n(j)*pi*v/L*t(k)); % no loop needed
end
us = sum(u);
plot(x,us)
end

• try to define all the variable before loop
• don't use clear all in your code. Calling clear all decreases code performance, and is usually unnecessary. To clear one or more specific variables from the current workspace use clearvars instead
clc
xs=8;
v=3;
L=20;
ta=0.2;
t=1:1:3;
n=1:1:40;
x=0:0.1:20;
us = zeros(1,length(x));
omga = zeros(1,length(n));
F = zeros(1,length(n));
u = zeros(length(n),length(x));
for k=1:length(t)
for j=1:length(n)
F(j)=exp(-((n(j)*pi*v*ta/L).^2)/4);
u(j,:)=sin(n(j)*pi*xs/L)*F(j)*sin(n(j)*pi*x/L)*cos(n(j)*pi*v/L*t(k)); % no loop needed
end
us(k,:) = sum(u);
end
plot(x,us);

what do you mean by video of these plots? you mean how one by one all your three plots are plotted?
here you can see some options: Get figures and use them to build a video.avi - (mathworks.com). You can also search on MATLAB File Exchange

Exactly, I want to build a video of all these plot. Thanks for sharing
