用matlab画奥运五环
可以使用 MATLAB 中的 `rectangle` 函数和 `fill` 函数来画奥运五环。
首先,我们需要定义五个圆环的半径和中心坐标。假设半径为 `r`,中心坐标为 `(x, y)`,则五环的参数可以定义如下:
```matlab
r = 50;
x1 = 0;
y1 = 0;
x2 = r * 2;
y2 = 0;
x3 = r * 4;
y3 = 0;
x4 = r;
y4 = r;
x5 = r * 3;
y5 = r;
```
接下来,我们可以使用 `rectangle` 函数画出五个圆环的轮廓框架:
```matlab
figure;
hold on;
axis equal;
rectangle('Position', [x1-r, y1-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x2-r, y2-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x3-r, y3-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x4-r, y4-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x5-r, y5-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
```
最后,我们使用 `fill` 函数填充五个圆环的颜色:
```matlab
fill([x1, x2, x3, x4, x5], [y1, y2, y3, y4, y5], ...
[0, 0.7, 0.9], 'EdgeColor', 'none'); % 蓝色
fill([x1+r, x2+r, x3+r, x4+r, x5+r], [y1, y2, y3, y4, y5], ...
[1, 0.7, 0], 'EdgeColor', 'none'); % 黄色
fill([x1-r, x2-r, x3-r, x4-r, x5-r], [y1, y2, y3, y4, y5], ...
[1, 0, 0], 'EdgeColor', 'none'); % 红色
fill([x1+r/2, x2+r/2, x3+r/2, x4+r/2, x5+r/2], [y1+r/2, y2+r/2, y3+r/2, y4+r/2, y5+r/2], ...
[0, 0.5, 0], 'EdgeColor', 'none'); % 绿色
fill([x1-r/2, x2-r/2, x3-r/2, x4-r/2, x5-r/2], [y1+r/2, y2+r/2, y3+r/2, y4+r/2, y5+r/2], ...
[1, 0, 1], 'EdgeColor', 'none'); % 紫色
```
完整代码如下:
```matlab
r = 50;
x1 = 0;
y1 = 0;
x2 = r * 2;
y2 = 0;
x3 = r * 4;
y3 = 0;
x4 = r;
y4 = r;
x5 = r * 3;
y5 = r;
figure;
hold on;
axis equal;
rectangle('Position', [x1-r, y1-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x2-r, y2-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x3-r, y3-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x4-r, y4-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
rectangle('Position', [x5-r, y5-r, r*2, r*2], 'Curvature', [1, 1], 'LineWidth', 5);
fill([x1, x2, x3, x4, x5], [y1, y2, y3, y4, y5], ...
[0, 0.7, 0.9], 'EdgeColor', 'none'); % 蓝色
fill([x1+r, x2+r, x3+r, x4+r, x5+r], [y1, y2, y3, y4, y5], ...
[1, 0.7, 0], 'EdgeColor', 'none'); % 黄色
fill([x1-r, x2-r, x3-r, x4-r, x5-r], [y1, y2, y3, y4, y5], ...
[1, 0, 0], 'EdgeColor', 'none'); % 红色
fill([x1+r/2, x2+r/2, x3+r/2, x4+r/2, x5+r/2], [y1+r/2, y2+r/2, y3+r/2, y4+r/2, y5+r/2], ...
[0, 0.5, 0], 'EdgeColor', 'none'); % 绿色
fill([x1-r/2, x2-r/2, x3-r/2, x4-r/2, x5-r/2], [y1+r/2, y2+r/2, y3+r/2, y4+r/2, y5+r/2], ...
[1, 0, 1], 'EdgeColor', 'none'); % 紫色
