How to draw random number from a Cauchy Distribution

I know random number can be drawn from a Normal Distribution as follows

normrnd(mu, sd)

where mu=mean and sd=standard deviation

But how can we draw a random number from Cauchy Distribution with given mu (location parameter) and sigma (scale parameter) as there is no built-in function available. For more information about Cauchy Distribution see this

Answer 1

[Roger Stafford]

To generate N random values of x with a Cauchy distribution where b is the half width at the half maximum density level and m is the statistical median:

   x = m+b*tan(pi*(rand(N,1)-1/2));
