Returns the Euclidean norm of a vector (returns ||x||_2). ARGUMENTS X float or complex matrix OPTIONS n integer. If n<0, the default value of n is used. The default value is equal to 1+(len(x)-offsetx-1)/incx or 0 if len(x) > offsetx+1 inc positive integer offset nonnegat
(X matrix.Matrix, opts ...linalg.Option)
