Based on DZASUM from the Level 1 BLAS. The change is to use the 'genuine' absolute value. .fi .PP .RE .PP \fBParameters:\fP .RS 4 \fIN\fP .PP .nf N is INTEGER The number of elements in the vector CX. .fi .PP .br \fICX\fP .PP .nf CX is COMPLEX*16 array, dimension (N) The vector whose elements will be summed. .fi .PP .br \fIINCX\fP .PP .nf INCX is INTEGER The spacing between successive values of CX.
