给我用matlab绘制小猪的图像

以下是使用 MATLAB 绘制小猪图像的示例代码：

% 定义小猪图像的参数
r1 = 50; % 头部半径
r2 = 25; % 身体半径
r3 = 10; % 眼睛半径
x0 = 0; y0 = 0; % 小猪中心点坐标
x1 = 30; y1 = -15; % 左耳朵坐标
x2 = -30; y2 = -15; % 右耳朵坐标
x3 = 20; y3 = 20; % 左眼睛坐标
x4 = -20; y4 = 20; % 右眼睛坐标

% 绘制小猪图像
theta = linspace(0, 2*pi, 100);
head_x = r1*cos(theta) + x0;
head_y = r1*sin(theta) + y0;
body_x = r2*cos(theta) + x0;
body_y = r2*sin(theta) + y0 - r1;
ear1_x = r3*cos(theta) + x1;
ear1_y = r3*sin(theta) + y1;
ear2_x = r3*cos(theta) + x2;
ear2_y = r3*sin(theta) + y2;
eye1_x = r3*cos(theta) + x3;
eye1_y = r3*sin(theta) + y3;
eye2_x = r3*cos(theta) + x4;
eye2_y = r3*sin(theta) + y4;
plot(head_x, head_y, 'LineWidth', 2); hold on;
plot(body_x, body_y, 'LineWidth', 2);
plot(ear1_x, ear1_y, 'LineWidth', 2);
plot(ear2_x, ear2_y, 'LineWidth', 2);
plot(eye1_x, eye1_y, 'LineWidth', 1);
plot(eye2_x, eye2_y, 'LineWidth', 1);
axis equal; axis([-60, 60, -60, 60]);

运行上述代码，即可生成小猪图像。您可以根据需要调整小猪图像的参数，例如头部半径、身体半径、眼睛半径等，以获得不同形态的小猪图像。
