写一个莱维飞行的matlab代码

好的，以下是莱维飞行的Matlab代码示例：

%% Generate random positions using Levy Flight
N = 1000; % number of positions to generate
alpha = 1.5; % Levy exponent
sigma = 0.1; % standard deviation of the Gaussian distribution
pos = zeros(N,2); % initialize position array with zeros
pos(1,:) = rand(1,2); % set initial position randomly
for k = 2:N
ds = abs(randn(1,2)*sigma); % distance step
dx = levy(alpha); % x-direction step from Levy distribution
dy = levy(alpha); % y-direction step from Levy distribution
dx = dx*ds(1)/norm([dx dy]); % scale x-direction step
dy = dy*ds(2)/norm([dx dy]); % scale y-direction step
pos(k,:) = pos(k-1,:) + [dx dy]; % update position
end

% Plot positions
figure;
plot(pos(:,1),pos(:,2),'b');
title('Levy Flight');
xlabel('x');
ylabel('y');

% Levy distribution function
function y = levy(alpha)
u = randn;
v = randn;
y = (u+v*1i)*abs(randn)^(1/alpha);
end
