matlab威布尔分布是两个参数
wblfit

Weibull parameter estimates
Syntax

parmhat = wblfit(data)
[parmhat,parmci] = wblfit(data)
parmhat,parmci] = wblfit(data,alpha)
[...] = wblfit(data,alpha,censoring)
[...] = wblfit(data,alpha,censoring,freq)
[...] = wblfit(...,options)
==========================
data = wblrnd(0.5,0.8,100,1);
[parmhat, parmci] = wblfit(data)
parmhat =
0.5861 0.8567
parmci =
0.4606 0.7360
0.7459 0.9973
