rv
class defined in
RNG.h
is a random variable whose default constructor
rv()
sets its seed number as the current time. There are
four probability density functions that can be used to select a
random number: uniform
, triangular
,
exponential
, normal
.
uniform(a,b)
returns a random number having a uniform
PDF over the closed interval [a,b]
.
triangular(a,b,c)
returns a random number having a
triangular PDF over the closed interval [a,b]
with mode
c
, where c
in [a,b]
.
exp(m)
returns a random number having an exponential
PDF with mean m
.
normal(m,s)
returns a random number having a normal
PDF with mean m
and standard deviation s
.
