Modules

module  pmc_rand
 Random number generators.
 

Functions/Subroutines

subroutine pmc_rand::pmc_srand (seed, offset)
 Initializes the random number generator to the state defined by the given seed plus offset. If the seed is 0 then a seed is auto-generated from the current time plus offset. More...
 
subroutine pmc_rand::pmc_rand_finalize ()
 Cleanup the random number generator. More...
 
real(kind=dp) function pmc_rand::pmc_random ()
 Returns a random number between 0 and 1. More...
 
integer function pmc_rand::pmc_rand_int (n)
 Returns a random integer between 1 and n. More...
 
integer function pmc_rand::prob_round (val)
 Round val to floor(val) or ceiling(val) with probability proportional to the relative distance from val. That is, Prob(prob_round(val) == floor(val)) = ceil(val) - val. More...
 
integer function pmc_rand::rand_poisson (mean)
 Generate a Poisson-distributed random number with the given mean. More...
 
integer function pmc_rand::rand_binomial (n, p)
 Generate a Binomial-distributed random number with the given parameters. More...
 
real(kind=dp) function pmc_rand::rand_normal (mean, stddev)
 Generates a normally distributed random number with the given mean and standard deviation. More...
 
subroutine pmc_rand::rand_normal_array_1d (mean, stddev, val)
 Generates a vector of normally distributed random numbers with the given means and standard deviations. This is a set of normally distributed scalars, not a normally distributed vector. More...
 
integer function pmc_rand::sample_cts_pdf (pdf)
 Sample the given continuous probability density function. More...
 
integer function pmc_rand::sample_disc_pdf (pdf)
 Sample the given discrete probability density function. More...
 
subroutine pmc_rand::sample_vec_cts_to_disc (vec_cts, n_samp, vec_disc)
 Convert a real-valued vector into an integer-valued vector by sampling. More...
 
character function pmc_rand::rand_hex_char ()
 Generate a random hexadecimal character. More...
 
subroutine pmc_rand::uuid4_str (uuid)
 Generate a version 4 UUID as a string. More...
 

Variables

integer, parameter pmc_rand::pmc_uuid_len = 36
 Length of a UUID string. More...
 
integer, parameter pmc_rand::pmc_rand_gsl_success = 0
 Result code indicating successful completion. More...
 
integer, parameter pmc_rand::pmc_rand_gsl_init_fail = 1
 Result code indicating initialization failure. More...
 
integer, parameter pmc_rand::pmc_rand_gsl_not_init = 2
 Result code indicating the generator was not initialized when it should have been. More...
 
integer, parameter pmc_rand::pmc_rand_gsl_already_init = 3
 Result code indicating the generator was already initialized when an initialization was attempted. More...
