TwoNorm(Int32, ArraySlice<Complex<T>>) 
TwoNorm(Int32, ArraySlice<Complex<T>>)

            Returns the euclidean norm of a vector via the function
            name, so that

TwoNorm(Int32, ReadOnlySpanSlice<Complex<T>>)

            Returns the euclidean norm of a vector via the function
            name, so that
               DZNRM2 := sqrt( x**H*x )

TwoNorm(Int32, ReadOnlySpan<T>, Int32)

            Returns the euclidean norm of a vector via the function
            name, so that
               DZNRM2 := sqrt( x**H*x )

TwoNorm(Int32, ReadOnlySpan<Complex<T>>, Int32)

            Returns the euclidean norm of a vector via the function
            name, so that
               DZNRM2 := sqrt( x**H*x )

TwoNorm(Int32, ReadOnlySpan<T>, Int32)

            Returns the euclidean norm of a vector via the function
            name, so that
