how could i animate this?

x=linspace(-5,5,1000);
a_n=2;
b_n=3;
l=10;
for n=1:1:10
    for t=0:1:10
        y=a_n*cos((n*pi*t)/l)+b_n*sin((n*pi*t)/l)*sin((n*pi*x)/l);
    end
end
u=y;

plot(x,u)

Hard to guess. What should be animated? Perhaps all you want to dois to move the plot command into the loops and add a pause(0.1) command.

that is right!

you need to know that there are several curves created in each loop iteration but you overwrite all the values and only the end values are saved in the last iteration

comet(x,u)

OR

x=linspace(-5,5,1000);
a_n=2;
b_n=3;
l=10;
for n=1:1:10
    for t=0:1:10
        y=a_n*cos((n*pi*t)/l)+b_n*sin((n*pi*t)/l)*sin((n*pi*x)/l);
        plot(x,y)
        pause(0.1)
    end
end
