scasum Return the sum of the absolute values of the elements
of x where x is an n-vector. This is the sum of the abso-
lute values of the real and complex elements and not the sum
of the squares of the real and complex elements.
N (input)
On entry, N specifies the number of elements in
the vector. N must be at least one for the sub-
routine to have any visible effect. Unchanged on
exit.
X (input)
( 1 + ( n - 1 )*abs( INCX ) ). On entry, the
incremented array X must contain the vector x.
Unchanged on exit.
INCX (input)
On entry, INCX specifies the increment for the
elements of X. INCX must not be zero or negative.
Unchanged on exit.
