Weibull mean and variance
[M,V] = wblstat(A,B)
[M,V] = wblstat(A,B) returns the mean of and variance for the Weibull distribution with scale parameter, A and shape parameter, B. Vector or matrix inputs for A and B must have the same size, which is also the size of M and V. A scalar input for A or B is expanded to a constant matrix with the same dimensions as the other input.
The mean of the Weibull distribution with parameters a and b is
and the variance is
