Conceptually, you can generate random numbers for any arbitrary distributions by
  1. Converting the pdf to a cdf.
  2. Generating uniform random numbers (from 0 to 1) using rand
  3. Mapping the uniform random numbers to the cdf.
There are many functions available on the file exchange that will do this for you.
