Matlab Tutorial on Sine Wave animated plot
To create an animated sine wave plot in MATLAB, you can use a loop to update the plot in real-time. Here’s a step-by-step example of how to create an animated sine wave:
MATLAB Code for Animated Sine Wave Plot
...............................................................................................................
% MATLAB Code to Create an Animated Sine Wave Plot
% Define parameters
A = 1; % Amplitude
B = 2 * pi / 10; % Frequency
C = 0; % Phase shift
speed = 0.1; % Speed of animation
% Define the range for x
x = linspace(0, 20, 1000);
% Create a figure
figure;
h = plot(x, A * sin(B * x + C), 'b-', 'LineWidth', 2);
title('Animated Sine Wave');
xlabel('x');
ylabel('y');
axis([0 20 -1.5 1.5]); % Set axis limits
grid on;
% Animation loop
while ishandle(h)
for k = 1:100
% Update the phase shift
C = C + speed;
% Update the y data
y = A * sin(B * x + C);
set(h, 'YData', y);
% Pause to create animation effect
pause(0.05);
end
end

Explanation
Parameters:
A: Amplitude of the sine wave.
B: Frequency of the sine wave.
C: Phase shift, which changes over time to animate the wave.
speed: Controls how quickly the wave animates.
Plot Setup:
x: Defines the range of x-values for the plot.
figure: Creates a new figure window.
plot: Plots the sine wave and sets initial properties.
Animation Loop:
while ishandle(h): Ensures that the loop continues as long as the figure is open.
for k = 1:100: Loops through a series of updates to create the animation effect.
C = C + speed: Updates the phase shift to animate the wave.
set(h, 'YData', y): Updates the y-data of the plot.
pause(0.05): Pauses briefly to control the animation speed.
Adjustments
speed: Change the speed of the animation by adjusting this value.
pause: Modify the pause duration to speed up or slow down the animation.
You can further enhance this animation by adding features such as labels, legends, or additional waveforms.
