<code>len</code> calculates the Euclidean length (also called Euclidean norm) of a vector or the
length of each column of a numeric matrix.

A collection of matrix functions for teaching and learning matrix
linear algebra as used in multivariate statistical methods. These functions are
mainly for tutorial purposes in learning matrix algebra ideas using R. In some
cases, functions are provided for concepts available elsewhere in R, but where
the function call or name is not obvious. In other cases, functions are provided
to show or demonstrate an algorithm. In addition, a collection of functions are
provided for drawing vector diagrams in 2D and 3D.
