dcabs1() double dcabs1 ( doublecomplex  z ) |Re(z)| + |Im(z)| (1-norm) (complex number) (BLAS 1) Purpose This routine computes the sum of the absolute values of real and imaginary part of a complex number (1-norm). Returns Sum of the absolute values of real and imaginary part of a complex number z (1-norm). Parameters [in] z Input complex number z. Reference BLAS
