rand
Format: rand( x1, x2 )
Arguments: (real) x1 Optional lower limit;
default = 0
(real) x2 Optional upper limit; default = 1
Returns: (real) Pseudo-random number between x1
and x2
Description: Rand generates a random number that is
equally likely to be any number between the lower and upper
limits (x1 <= rand < x2).
The sequence of numbers generated by rand has a period
that is essentially infinite. Also, there are no sensible
sequential correlations. The random numbers have a granularity of
better than 1e-10.
Examples: rand = random
number between 0 and 1
rand(5,10) = random number
between 5 and 10, PDF graphed below
