From plot to video

Hi all,

I have done this code and I obtain a plot of graphs where every graph represent the result at a different second. How can I translate this in a video where the graphs appear subsequently one by one? is it possible to obtain it in a video format?

clear
T0=293
s=1

alfa=0.005

for a=1:1:21
    t=0:1:20
    for b=1:1:21
        x=0:0.05:1
        for n=1:1:100
            
        T=(2.*T0./pi).*((1-((-1).^n))./n).*exp(-((n.*pi./s).^2).*alfa.*t(:,a)).*(sin(pi.*n.*x(:,b)./s))
        
        Tn1(:,n)=T
        Tn=sum(Tn1)
        end
        Tb(:,b)=Tn
    end
Tab(:,a)=Tb
end

plot(x,Tab)

See getframe() https://www.mathworks.com/help/matlab/ref/getframe.html and videowriter() https://www.mathworks.com/help/matlab/ref/videowriter.html

I tried to place this code at the end of my code, but nothing works.

F = getframe;
figure
imshow(F.cdata)

fig = figure();
ax = axes(fig);

T0 = 293;
s = 1;

alfa = 0.005;

t = 0:1:20;
x = 0:0.05:1;

for a = 1:1:21
    for b = 1:1:21
        for n = 1:1:100
            T = (2.*T0./pi).*((1-((-1).^n))./n).*exp(-((n.*pi./s).^2).*alfa.*t(:,a)).*(sin(pi.*n.*x(:,b)./s));
            Tn1(:,n) = T;
        end
        Tn = sum(Tn1);
        Tb(:,b) = Tn;
    end
    Tab(:,a) = Tb;
end

plot(ax, x,Tab)
F = getframe(ax);
exportgraphics(ax, 'test_export.png');

figure();
imshow(F.cdata)

At the moment I do not know why only the inside of the axes is being captured.

figure();
imshow('test_export.png')

but exportgraphics() gets it all.
