matlab有趣的代码

当然！ MATLAB 有很多有趣的代码。以下是一些示例：

1. 彩色螺旋矩阵：

n = 100;
A = zeros(n);
x = 1;
y = 1;
direction = 0;steps = n;
for k = 1:n^2
    A(x, y) = k;
    if x == y || (x < n/2+1 && x == n-y+1) || (x > n/2 && x == n-y)
        direction = mod(direction + 1, 4);
    end
    if direction == 0
        y = y + 1;
    elseif direction == 1
        x = x + 1;
    elseif direction == 2
        y = y - 1;
    else
        x = x - 1;
    end
    steps = steps - 1;
    if steps == 0
        if direction == 0 || direction == 2
            steps = n - ceil(n/2);
        else
            steps = n - floor(n/2);
        end
    end
end

imagesc(A);
colormap(jet);

2. 绘制曼德勃罗集：

[X,Y] = meshgrid(-2:0.005:1,-1.2:0.005:1.2);
Z = X + 1i*Y;
C = Z;
Z = zeros(size(Z));for n = 1:100
    Z = Z.^2 + C;
end
M = abs(Z) < 100;
imagesc(M);
colormap(jet);

3. 创建一个动态的球体：

[X,Y,Z] = sphere(50);
figure;
h = surf(X, Y, Z);
axis equal;
axis off;

frames = 100;
for i = 1:frames
    rotate(h, [0,0,1], 360/frames);
    drawnow;
end

这只是几个简单的例子，MATLAB 还有很多有趣的代码和功能可供探索。希望你喜欢！
