Overload List

TwoNorm(Int32, ArraySlice<T>)

            Returns the euclidean norm of a vector via the function
            name, so that
               DNRM2 := sqrt( x'*x )

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

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

TwoNorm(Int32, ArraySlice<T>)

            Returns the euclidean norm of a vector via the function
            name, so that
               DNRM2 := sqrt( x'*x )

C# 
public override T TwoNorm(
	int n,
	ArraySlice<T> x
)

Parameters
