Number of initial points to omit from sequence
Skip property of a point set contains
a positive integer which specifies the number of initial points in
the sequence to omit from the point set. The default
Initial points of a sequence sometimes exhibit undesirable properties,
for example the first point is often
this may "unbalance" the sequence since its counterpart,
never appears. Another common reason is that initial points often
exhibit correlations among different dimensions which disappear later
in the sequence.
Examine the difference between skipping and not skipping points:
% No skipping produces the standard Sobol sequence. P = sobolset(5); P(1:3,:) % Skip the first point of the sequence. The point set now % starts at the second point of the basic Sobol sequence. P.Skip = 1; P(1:3,:)
