Fit weibull distribution matlab
WebSupported Distributions Statistics and Machine Learning Toolbox™ supports various probability distributions, including parametric, nonparametric, continuous, and discrete distributions. The following tables list the supported probability distributions and supported ways to work with each distribution. WebDescription p = wblcdf (x,a,b) returns the cdf of the Weibull distribution with scale parameter a and shape parameter b, at each value in x. 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.
