lrand

Format: lrand( mean, std )

Arguments: (real) mean Optional distribution mean; default = 1

(real) std Optional distribution standard deviation; default = 1

Returns: (real) Pseudo-random number from a lognormal distribution

Description: Lrand generates random numbers that are drawn from a set with a lognormal probability distribution. The sequence of numbers generated by lrand has a period that is essentially infinite. Also, there are no sensible sequential correlations.

Examples: lrand = random number with a mean of 1 and a standard deviation of 1

lrand(10,5) = random number with a mean of 10 and a standard deviation of 5, PDF graphed below
