# movie

Render recorded movie frames.

## 📝 Syntax

* movie(M)
* movie(M, n)
* movie(M, n, fps)
* movie(h, ...)

## 📥 Input argument

* M - structure array: Array of movie frames.
* n - numeric scalar: Number of times to play movie: default 1.
* fps - numeric scalar: Frames per second : default 12.
* h - Graphics object handle: default: gca()

## 📄 Description

movie(M) plays the frames stored in the array M once. To capture a movie frame from the current figure or axes, use getframe.

movie(M, n) replays the movie n times. If n is a numeric array, the first element determines the number of repetitions, while the remaining elements define the sequence of frames to display.

movie(M, n, fps) sets the playback speed to fps frames per second.

movie(h, ...) displays the movie centered within the figure or axes specified by h, adjusting the movie size to fit the available space.

## 💡 Examples

```matlab
% Create a figure
fig = figure('Visible', 'off');

% Number of frames
numFrames = 20;

% Preallocate an array of movie frames
clear('M');
M(numFrames) = struct('cdata', [], 'colormap', []);

% Generate frames with a moving circle
theta = linspace(0, 2*pi, numFrames); % Angle for movement

for k = 1:numFrames
    % Clear the figure
    clf;

    % Plot a moving circle
    x = cos(theta(k));
    y = sin(theta(k));
    plot(x, y, 'ro', 'MarkerSize', 10, 'MarkerFaceColor', 'r');

    % Set axis limits
    axis([-1.5 1.5 -1.5 1.5]);
    axis equal;
    grid on;

    % Capture the frame
    M(k) = getframe(fig);
end
close(fig);

% Play the recorded movie 3 times at 10 frames per second
figure();
movie(M, 3, 10);
```

```matlab
examples_directory = [modulepath('graphics', 'root'), '/', 'examples/'];
edit([examples_directory, 'movie/demo_movie.m']);
run([examples_directory, 'movie/demo_movie.m']);
