Random Numbers
Pseudorandom numbers
are generated by deterministic algorithms. They are "random"
in the sense that, on average, they pass statistical tests regarding
their distribution and correlation. They differ from true random numbers
in that they are generated by an algorithm, rather than a truly random
process. Random number generators (RNGs),
like those in MATLAB are algorithms for generating pseudorandom
numbers with a specified distribution. A given number may be repeated
many times during the sequence, but the entire sequence
is not repeated.
A pseudorandom sequence is described by several properties.
A random stream is the sequence of values that
are returned by a generator. The period of a
sequence is its length, that is, the number of values it generates
before the entire sequence is repeated. The state is
the information the generator keeps internally in order to create
successive values in the stream. The seed of
a sequence is a single value to define its starting point.
