Animation of plot upon changing parameter
显示 更早的评论
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
Use the `pause` function to pause the execution of the code for 0.1 seconds between each frame, creating the appearance of an animation.
Adjust the time range, and `pause` time as needed to create an animation that displays the changing plot of your function over time.
