用matlab绘制带飘动效果的五星红旗的代码

以下是用MATLAB绘制带飘动效果的五星红旗的示例代码：

% 设置画布大小
width = 480;
height = 320;

% 创建画布
hFig = figure('Position', [100 100 width height]);
hAx = axes('Parent', hFig, 'Position', [0 0 1 1]);

% 绘制五星红旗
red = [1 0 0];
yellow = [1 1 0];
star = [0.8 0.8 0.8];
stripe_height = height / 15;
stripe_width = stripe_height * 10;
flag_width = stripe_width * 1.5;
flag_height = stripe_height * 10;
x = -flag_width / 2;
y = -flag_height / 2;
rectangle(hAx, 'Position', [x y flag_width flag_height], 'FaceColor', red, 'EdgeColor', 'none');
hold on;
for i = 1:2:10
    rectangle(hAx, 'Position', [x y + i * stripe_height stripe_width stripe_height], 'FaceColor', yellow, 'EdgeColor', 'none');
end
for i = 1:2:8
    rectangle(hAx, 'Position', [x + stripe_width y + i * stripe_height stripe_width stripe_height], 'FaceColor', yellow, 'EdgeColor', 'none');
end
rectangle(hAx, 'Position', [x y stripe_width stripe_height * 2], 'FaceColor', yellow, 'EdgeColor', 'none');
rectangle(hAx, 'Position', [x y + stripe_height * 6 stripe_width stripe_height * 4], 'FaceColor', star, 'EdgeColor', 'none');
theta = pi / 10;
r = stripe_height * 1.5;
x0 = 0;
y0 = 0;
x1 = r * sin(theta);
y1 = r * cos(theta);
for i = 1:5
    x2 = x0 + (x1 - x0) * cos(theta) - (y1 - y0) * sin(theta);
    y2 = y0 + (x1 - x0) * sin(theta) + (y1 - y0) * cos(theta);
    line(hAx, [x1 x2], [y1 y2], 'Color', yellow, 'LineWidth', 2);
    x1 = x2;
    y1 = y2;
end

% 设置飘动效果
amplitude = stripe_height / 4;
frequency = 2;
phase = pi / 2;
flag_x = x;
flag_y = y;
time = 0;
while ishandle(hFig)
    flag_y = y + amplitude * sin(2 * pi * frequency * time + phase);
    set(hAx.Children, 'Position', [flag_x flag_y flag_width flag_height]);
    drawnow;
    time = time + 0.02;
end

这段代码会生成一个窗口，其中绘制了带飘动效果的五星红旗。你可以根据自己的需要修改绘制参数来调整红旗的大小和飘动效果的幅度和频率。
