You need to use inverse transform sampling. I attached a demo where I use it to get random numbers from a Rayleigh distribution.

Hi Thanks,
It turns out if I have to use your inverse transformation then I need to integrate PDF to get CDF and then I can consider CDF as uniform number apply your technique. Thanks for this code it solved my problem.
