plgen - generate samples from a power-law distribution

plgen [ OPTIONS ] num_samples gamma [ kappa ]

Generates a given number of samples from a power-law distribution with an optional exponential cutoff. The pdf being sampled is given as follows:

P(k) = C * kˆ( -gamma ) * exp( -k /kappa)

where C is an appropriate normalization constant. gamma is given by the second command line argument, kappa is given by the -k switch.

	-h		shows this help message
	-v		shows version information
	-c		generate continuous samples

-k KAPPA

use exponential cutoff with kappa = KAPPA

-o OFFSET

add OFFSET to each generated sample

-s SEED

use SEED to seed the random number generator

-x XMIN

generate a power-law distribution that starts at XMIN
