%description
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.
