double dasum(int n, double *x, int incx);
double dasum_64(long n, double *x, long incx);
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 or negative.
Unchanged on exit.
