7.3.7  Producing random numbers with an exponential distribution: randexp

Recall that given a positive number a, the corresponding exponential distribution satisfies

Prob(X ≤ t) = a 
t


0
 exp(−a * udu

Given a parameter a, the command randexp(a) will return a number chosen randomly according to the corresponding exponential distribution. For example, if you enter

randexp(1)

you might get

0.193354391918
