Hello! I have a code and a set of pictures at different values of parameter t. Is it possible to make an animation to see how the plot changes with changing time (t=0:3)? If somebody knows how, please, help me. Thank you.

s = 3;

n = 1;

t = 0.1;

r = 1;

a = 0:1:360;

a = a*pi/180;

b = sqrt(2*n*t);

L = sqrt((4*t+r^2)/3);

fun = @(k,u,c,a) ((k.^2).*exp(-1.5*k.^2)).*((u.^2).*(1-u.^2).*exp(-(b.*u).^2).*(cos(s.*k.*u.*cos(a)/L))).*(((cos(c)).^2).*(cos(s.*k.*sqrt(1-u.^2).*sin(a).*(cos(c)+sin(c))/(L*sqrt(2)))));

f3 = arrayfun(@(a)integral3(@(k,u,c)fun(k,u,c,a),0,Inf,-1,1,0,2*pi),a);

B = ((6*sqrt(6)*b^3)/(erf(b)*pi^2))*(1-(3/(2*b^2))*(1-((2*b*exp(-b^2))/(erf(b)*sqrt(pi))))).^(-1);

R = B*f3;

polar(a,R);

Hi Hexe,

I understand that you want to to make an animation to see how the plot changes with changing time.

Yes, it is possible to create an animation in MATLAB to see how a plot changes over time by looping through a sequence of plots and using the `pause` function to control the speed of the animation.

Here's an example of how to create an animation to display a plot of a function across time in MATLAB:

% Define function and time range
t = 0:0.1:3;
x = linspace(-2, 2);
y = zeros(length(x), length(t));
for k = 1:length(t)
    y(:, k) = sin(x + t(k));
end
% Create animated plot
figure;
for k = 1:length(t)
    plot(x, y(:, k));
    xlabel('x');
    ylabel('y');
    title(sprintf('t = %0.1f', t(k)));
    ylim([-1.5, 1.5]);
    pause(0.1);
end
