CLUSFLT (3sciport)

Searches a real vector for clusters of elements which are less than a real target value

SYNOPSIS

  Call CLUSFLT( n, x, incx, target, index, nn )

ARGUMENTS

  n               Integer.
                  The number of elements to be searched.

  x               Real vector.
                  The real input vector to be searched.

  incx            Integer.
                  The increment between elements of vector x. For contiguous
                  elements, incx = 1.

  target          Real.
                  The target value searched for in array x.

  index           Integer vector.
                  An output integer vector containing pairs of indices. The
                  first member of each pair holds the starting index of a
                  cluster of elements in vector x that are less than target.
                  The second member of each pair contains the ending index of
                  a cluster.

  nn              Integer.
                  The number of clusters found in vector x.

DESCRIPTION

  Subroutine CLUSFLT returns the locations of clusters of elements within
  vector x that are less than target. Cluster locations are recorded in
  integer vector index as pairs of beginning and ending indices.
