dasum Return the sum of the absolute values of x where x is
an n-vector.
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. Unchanged
on exit.
