Dznrm2() Function Dznrm2 ( N As  Long, ZX_I As  Complex, Optional IncX As  Long = 1  ) ||x||2 (2-norm) (complex vector) (BLAS 1) Purpose This routine computes the Euclidean norm of a complex vector (2-norm). Returns Double Euclidean norm of a complex vector x (= sqrt(x^H*x)) (2-norm). Parameters [in] N Number of elements in vector x. (If N <= 0, returns 0) [in] ZX_I An element X(I) of the array X(). Starting from this location, vector x is stored with element spacing IncX. [in] IncX (Optional) Element spacing of vector x in array X(). (If IncX <= 0, returns 0) (default = 1) Reference BLAS
