create a animation with symbolic expression in matlab

To create an animation with symbolic expression in MATLAB, you can follow these steps:

1. Define your symbolic expression using the syms function. For example, let's say you want to animate the function f(x) = sin(x). You would define it using:

main.m
syms x;
f = sin(x);

2. Define the values for the independent variable that you want to use for the animation. For example, let's say you want to animate the function for values of x between 0 and 2*pi in steps of 0.1. You would define it using:

main.m
x_values = 0:0.1:2*pi;

3. Create the animation using a loop. For each iteration of the loop, evaluate the symbolic expression for the current value of x, and plot the result. Use the pause function to add a small delay between frames to create a smooth animation. For example:

main.m
for i = 1:length(x_values)
    clf; % Clear the figure
    x = x_values(i); % Set the value of x for this iteration
    y = double(subs(f)); % Evaluate the symbolic expression for the current value of x
    plot(x,y,'o'); % Plot the result
    xlim([0 2*pi]); % Set the x-axis limits
    ylim([-1 1]); % Set the y-axis limits
    pause(0.01); % Add a small delay to create a smooth animation
end

This will create an animation where the function is plotted for values of x between 0 and 2*pi, and the point moves along the curve as x changes. You can modify this code to create different types of animations with symbolic expressions.
