Overload List

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

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

TwoNorm<T, TStorage>(ILinearAlgebraOperations<T>, Int32, TStorage) Returns the square root of sum of the squares of the elements of a vector.

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

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

C# 
public static T TwoNorm<T>(
	this ILinearAlgebraOperations<T> operations,
	int n,
	ReadOnlySpanSlice<T> x
)

Parameters
