NAME

       plgen - generate samples from a power-law distribution

SYNOPSIS

       plgen [OPTIONS] num_samples gamma [kappa]

DESCRIPTION

       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 * k^(-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.

OPTIONS

       -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
