用matlab写一个可以在simulink中运行的函数该函数可以对输入的天数和失效率数据进行Weibull分布拟合

function [a, b] = weibull_fit(days, failure_rates) % WEIBULL_FIT fits Weibull distribution to input data and returns % shape and scale parameters % % Syntax: [a, b] = weibull_fit(days, failure_rates) % % Inputs: % - days: vector of days % - failure_rates: vector of corresponding failure rates % % Outputs: % - a: shape parameter of Weibull distribution % - b: scale parameter of Weibull distribution

% Convert failure rates to failure probabilities failure_probs = 1 - exp(-failure_rates.*days);

% Fit Weibull distribution to failure probabilities params = wblfit(failure_probs);

% Extract shape and scale parameters a = params(1); b = params(2);

end

% To use this function in Simulink, create a MATLAB Function block, % copy and paste the code above, and connect the inputs and outputs.
