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.
