The ?cabs1 is an auxiliary routine for a few BLAS Level 1 routines. This routine performs an operation defined as
where z is a scalar, and res is a value containing the absolute value of a complex number z.
COMPLEX scalar for scabs1.
DOUBLE COMPLEX scalar for dcabs1.
REAL for scabs1.
DOUBLE PRECISION for dcabs1.
Contains the absolute value of a complex number z.
