This function wraps a call to the standard Octave
function rande, which is redefined by
RcppOctave to call the R base function
rexp. This enables to exactly
reproduce stochastic computations in R and Octave,
without changing the original Octave/Matlab code. See
o_runif for more details.
o_rexp(n, p = n)
n)USAGE: E = rande( n [, k]) Generates standard-exponential random variatesas R function 'rexp' -- using the current RNG from R. Possible calls: rande(n, k) returns n*k matrix with uncorrelated E(0, 1) deviates drawn in columns rande(n) returns n*n matrix with uncorrelated E(0, 1) deviates drawn in columns NOTE: This function substitutes Octave original function in calls from RcppOctave
