How to generate the Weibull's parameters k and c in Matlab?

问题

Can anyone explain to me how to generate the Weibull distribution parameters k and c, in Matlab?

I have a file of 8000 data of wind speed, and I'd like to do the following:

1. Generate the Weibull's k and c parameters of those.
2. Plot the probability density function against the wind speed.

I am new in Matlab and have not yet been able to do this.

If you have the Statistics toolbox, you can use fitdist:

pd = fitdist(x,'Weibull')

where x is your data. I'm guessing it should return the parameters a and b in:

You can then calculate the pdf (and plot it) using the pdf function. There are some examples (albeit for a normal distribution) in the documentation for fitdist.
