def dnrm2(x, n = None, offx = 0, incx = 1)

Summary

Compute the Euclidean norm sqrt(sum(abs(x)**2)) (BLAS dnrm2).

Parameters

x : ndarray: Input vector.
n : int, optional: Number of elements to process. Default is the whole vector.
offx : int, optional: Index of the first element of x to use. Default is 0.
incx : int, optional: Stride between successive elements of x. Default is 1.

Returns

nrm : float: The Euclidean norm of x.
