Computes the non-zero part of an Unbalanced Haar vector with a given start-, break-
and end-point.
Usage
unbal.haar.vector(a)
Arguments
a
a three-component vector of integers such that a[1] <= a[2] < a[3].
The three components specify, respectively, the start point, the time point just before the breakpoint,
and the endpoint of the desired Unbalanced Haar vector.
Value
the non-zero part of the corresponding Unbalanced Haar vector
