reset
Reset state
Syntax
reset(q)
Description
reset(q)
resets the state of the quasi-random number stream
q
of the qrandstream
class back to its initial state,
1
. Subsequent points drawn from the stream will be the same as
those drawn from a new stream. The command is equivalent to q.State =
1
.
Examples
Use qrandstream
to construct a 3-D Halton
stream, based on a point set that skips the first 1000 values and then retains every
101st point:
q = qrandstream('halton',3,'Skip',1e3,'Leap',1e2) q = Halton quasi-random stream in 3 dimensions Point set properties: Skip : 1000 Leap : 100 ScrambleMethod : none nextIdx = q.State nextIdx = 1
Use qrand
to generate two samples of size
four:
X1 = qrand(q,4) X1 = 0.0928 0.3475 0.0051 0.6958 0.2035 0.2371 0.3013 0.8496 0.4307 0.9087 0.5629 0.6166 nextIdx = q.State nextIdx = 5 X2 = qrand(q,4) X2 = 0.2446 0.0238 0.8102 0.5298 0.7540 0.0438 0.3843 0.5112 0.2758 0.8335 0.2245 0.4694 nextIdx = q.State nextIdx = 9
Use reset
to reset the stream, then generate another
sample:
reset(q) nextIdx = q.State nextIdx = 1 X = qrand(q,4) X = 0.0928 0.3475 0.0051 0.6958 0.2035 0.2371 0.3013 0.8496 0.4307 0.9087 0.5629 0.6166
