Given an
-element complex vector
, and real scalars
and
,
f06kjf
returns updated values
and
such that
f06kjf is designed for use in the safe computation of the
Euclidean norm of a complex vector, without unnecessary overflow or destructive underflow. An initial call to
f06kjf
(with
and
)
may be followed by further calls to
f06kjf and finally a call to
f06bmf to complete the computation. Multiple calls of
f06kjf may be needed if the elements of the vector cannot all be accessed in a single array
x.
