Generating signal from weibull distribution

Hi, i have a Weibull distribution that is representative of wind speed data and I want to create a continious signal in MATLAB to recall in a Simulink model. I tried with the function wblrnd putting in the scala and form parametres but i failed to create the signal itself.

Hi, in what form do you have the Weibull distribution? Seems like you need an m-file representing the function, right?

Hi Davide,
The functions wblpdf and wblrnd are both eligible for code generation, so you can call either from inside a Matlab Function block without too much trouble. However, if you use wblrnd that way I have no idea which random stream is used nor how you can control that stream, e.g., for Simulink run repeatbility.
Another option would be to implement inverse sampling in the model, which could probably very well approximate a Weibull distribution and has the advantage of using the Uniform Random Number block for which you can control the seed.
