NAME
scasum - Return the sum of the absolute values of a vector
x.
SYNOPSIS
REAL FUNCTION SCASUM (N, X, INCX)
INTEGER INCX, N
COMPLEX X( * )
#include <sunperf.h>
double scasum(int n, complex *cx, int incx) ;
PURPOSE
SCASUM - Return the sum of the absolute values of the ele-
ments of x where x is an n-vector. This is the sum of the
absolute values of the real and complex elements and not the
sum of the squares of the real and complex elements.
PARAMETERS
N - INTEGER.
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 - COMPLEX array of DIMENSION at least
( 1 + ( m - 1 )*abs( INCY ) ). On entry, the
incremented array X must contain the vector x. On
exit, X is overwritten by the updated vector x.
INCX - INTEGER.
On entry, INCX specifies the increment for the
elements of X. INCX must not be zero. Unchanged
on exit.
