CLUSFGT (3sciport)


SYNOPSIS

  Call CLUSFGT( 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 greater 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 CLUSFGT returns the locations of clusters of elements within
  vector x that are greater than target. Cluster locations are recorded in
  integer vector index as pairs of beginning and ending indices.
