把以上方法变成matlab仿真代码

以下是一份MATLAB仿真代码，用于实现最大化星座内任意两颗卫星之间的距离的卫星分布优化问题：

N = 10; % 卫星数量
P = 1; % 轨道面
m = 1; % 协因子
a = 6378.137 + 500; % 卫星轨道高度
i = 0; % 轨道倾角
e = 0; % 离心率
omega = 0; % 近地点幅角
mu = 398600.4418; % 地球引力常数

% 计算升交点赤经和初始相位
alpha = zeros(N, 1);
gamma = zeros(N, 1);
for j = 1:N
    alpha(j) = 2 * pi * (j - 1) / N;
    gamma(j) = 2 * pi * rand;
end

% 计算卫星位置和方向
r = zeros(N, 3);
v = zeros(N, 3);
for j = 1:N
    r(j, :) = a * [cos(alpha(j)) * cos(gamma(j)) - sin(alpha(j)) * sin(gamma(j)) * cos(i), sin(alpha(j)) * cos(gamma(j)) + cos(alpha(j)) * sin(gamma(j)) * cos(i), sin(i) * sin(gamma(j))]';
    v(j, :) = sqrt(mu / norm(r(j, :))) * [-sin(alpha(j)) * sin(gamma(j)) - cos(alpha(j)) * cos(gamma(j)) * cos(i), cos(alpha(j)) * sin(gamma(j)) - sin(alpha(j)) * cos(gamma(j)) * cos(i), sin(i) * cos(gamma(j))]';
end

% 计算任意两颗卫星之间的距离
d = zeros(N, N);
for j = 1:N
    for k = 1:N
        if j ~= k
            d(j, k) = norm(r(j, :) - r(k, :));
        end
    end
end

% 最大化任意两颗卫星之间的距离
f = 0;
for j = 1:N
    for k = 1:N
        if j ~= k
            f = f - 1 / d(j, k);
        end
    end
end

% 输出最优的卫星分布方案
options = optimoptions('fmincon', 'Display', 'iter');
[x, fval] = fmincon(@(x) myfun(x, d), rand(N * 2, 1), [], [], [], [], zeros(N * 2, 1), [ones(N, 1) * 2 * pi, ones(N, 1)], [], options);
for j = 1:N
    alpha(j) = x(j);
    gamma(j) = x(j + N);
    r(j, :) = a * [cos(alpha(j)) * cos(gamma(j)) - sin(alpha(j)) * sin(gamma(j)) * cos(i), sin(alpha(j)) * cos(gamma(j)) + cos(alpha(j)) * sin(gamma(j)) * cos(i), sin(i) * sin(gamma(j))]';
end

% 显示卫星分布结果
figure;
hold on;
grid on;
plot3(r(:, 1), r(:, 2), r(:, 3), 'o');
axis equal;
xlabel('X');
ylabel('Y');
zlabel('Z');
title('卫星分布结果');

function f = myfun(x, d)
    N = length(d);
    alpha = x(1:N);
    gamma = x(N + 1:end);
    r = zeros(N, 3);
    for j = 1:N
        r(j, :) = [cos(alpha(j)) * cos(gamma(j)), sin(alpha(j)) * cos(gamma(j)), sin(gamma(j))]';
    end
    f = 0;
    for j = 1:N
        for k = 1:N
            if j ~= k
                f = f - 1 / norm(r(j, :) - r(k, :));
            end
        end
    end
end

这份代码首先定义了卫星数量N、轨道面P、协因子m和卫星轨道高度a等参数，然后计算出每个卫星的升交点赤经和初始相位。接着，通过计算每个卫星的位置和方向，以及任意两个卫星之间的距离，最终将卫星分布问题转化为最大化任意两颗卫星之间的距离。最后，通过调用MATLAB中的fmincon函数，求解最优的卫星分布方案，并将结果显示出来。
