ArbRand.m

Arbitrary distribution random number generator.

There are three optional inputs. first two inputs are the output matrix size specification parameters 'rows' and 'cols'. Third and last input is the user specified probability density function. This has to be have a range normalised between 0 and 1.
Default value for both 'rows' and 'cols' is 1. Default value for the probability density function is a monotonous triangular probability density function.
