CLUSFGE (3sciport)

Searches a real vector for clusters of elements which are greater than or equal to a real target value

SYNOPSIS

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