ISRCHFLT (3sciport)

Searches a real vector for the first entry less than a real target

SYNOPSIS

  location = ISRCHFLT( n, x, incx, target )

FUNCTION VALUE

  isrchflt        Integer.
                  The location in vector x of the first element less than
                  target.

ARGUMENTS

  n               Integer.
                  The number of elements to be searched. If n <= 0, then 0 is
                  returned.

  x               Real vector.
                  A real input array to be searched.

  incx            Integer.
                  The increment between elements of the array to be searched.
                  For contiguous elements, incx = 1.

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

DESCRIPTION

  The function ISRCHFLT returns the first location in real vector x that is
  less than a real target. If all elements of vector x are greater than or
  equal to target, then the returned value is n+1.
