Weibull probability density function
Y = wblpdf(X,A,B)
Y = wblpdf(X,A,B) computes the Weibull pdf at each of the values in X using the corresponding scale parameter, A and shape parameter, B. X, A, and B can be vectors, matrices, or multidimensional arrays that all have the same size. A scalar input is expanded to a constant array of the same size as the other inputs. The parameters in A and B must be positive.
The Weibull pdf is
Some references refer to the Weibull distribution with a single parameter. This corresponds to wblpdf with A = 1.
The exponential distribution is a special case of the Weibull distribution.
