To generate non-uniform data points

Hi all,

I have a query regarding generation of non uniform data points .

rand(m,n):It generates a mxn matrix of uniformly distributed pseudorandom numbers between{0,1}.

As I require non-uniformally distributed data points (e.g. random C shaped networks), how can i achieve this or which function to be used.

If you have the statistics toolbox you can use random to generate random numbers from a distribution that you'd specify (with makedist or fitdist).

Otherwise, you'll have to start with a uniform random distribution or normal random distribution (i.e. rand or randn, respectively) and rescale to your distribution. This is what random does anyway.
