setrl
setrl (v) set random link
rand01
rand01 (v) generate y random numbers in interval (0,1)
rand11
rand11 (v) generate y random numbers in interval (_1,1)
randomize
randomize (v) sets a random value into random link
deal
deal (v) deal x items from y (no repetition)
dealx
dealx (v) deal x indices from shape y (no repetition)
toss
toss (v) pick x items from y (with repetition)
tossx
tossx (v) pick x indices from shape y (with repetition)
betarand
betarand (v) random numbers in a beta distribution
y has 3 elements p,q,n 0 = power parameter 1 = power parameter 2 = number of trials
binomialrand
binomialrand (v) random numbers 0 and 1 in binomial distribution
y has 2 elements: 0 = probability of success in one trial 1 = number of trials
cauchyrand
cauchyrand (v) random numbers in a cauchy distribution
with F(x)=0.5+(arctan x)%o.1 y = number of trials
discreterand
discreterand (v) random numbers in a discrete distribution
y has two elements 0 = 2-row matrix: 0 = discrete values 1 = corresponding probabilities 1 = number of trials
exponentialrand
exponentialrand (v) random numbers in an exponential distribution
with mean=1. F(x)=1-^-x y = number of trials
gammarand
gammarand (v) random numbers in a gamma distribution
y has 2 elements p,n 0 = power parameter 1 = number of trials if p=1 this is the exponential distribution
normalrand
normalrand (v) random numbers in a standard normal distribution,
with mean=0, standard deviation=1. y = number of trials.
poissonrand
poissonrand (v) random numbers in a poisson distribution
y has 2 elements: 0 = mean of distribution (=variance) 1 = number of trials
