create an animation in a subplot in matlab

To create an animation in a subplot in MATLAB, you can use a loop to update the plot data in each frame. Here's an example code that creates a subplot animation:

main.m
% Create plot data
t = linspace(0, 2*pi, 100);
x = sin(t);

% Create subplot
subplot(2, 1, 1);
plot(t, x);
ylim([-1.5 1.5]);
title('Original Plot');

% Create animation subplot
subplot(2, 1, 2);
h = plot(NaN, NaN); % create empty plot object
ylim([-1.5 1.5]);
title('Animated Plot');

% Loop animation frames
for i = 1:length(t)
    % Update plot data
    y = sin(t(i));
    set(h, 'XData', t(1:i), 'YData', x(1:i)); % update plot object
    drawnow; % force plot refresh
    pause(0.1); % pause for animation effect
end

In this example, the subplot function is used to create two subplots, each with their own title. The plot function is used to create the original plot data in the top subplot. A second plot function call creates an empty plot object in the animation subplot, which will be updated in each frame of the animation.

The animation loop iterates over all the t values and updates the set properties of the plot object in each frame. The drawnow function is called in each frame to force a refresh of the plot, and a pause function is called to create the animation effect.
