WHENFLE (3sciport)

Searches a real vector for all elements which are less than or equal to a real target value

SYNOPSIS

  Call WHENFLE( 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 integer output vector containing the indices of all
                  elements in vector x which are less than or equal to the
                  target value.

  nn              Integer.
                  The number of elements in vector x which are less than or
                  equal to the target value.

DESCRIPTION

  Subroutine WHENFLE returns all locations in real array x that are less than
  or equal to target. The locations are returned in integer vector index.
