vectorNorm3d

PURPOSE

SYNOPSIS

DESCRIPTION

VECTORNORM3D Norm of a 3D vector or of set of 3D vectors.

   N = vectorNorm3d(V);
   Returns the norm of vector V.

   When V is a N-by-3 array, compute norm for each vector of the array.
   Vectors are given as rows. Result is then a N-by-1 array.

   NOTE: Computes only the Euclidean norm.
