matlib: Matrix Functions for Teaching and Learning Linear Algebra and Multivariate Statistics.
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, sometimes
verbose argument to print the details of computations.
In addition, a collection of functions are provided for drawing vector diagrams in 2D and 3D.
These are not meant for production uses. Other methods are more efficient for larger problems.
The functions in this package are grouped under the following topics
Gaussian elimination: functions for illustrating Gaussian elimination for solving systems of linear equations of the form $A x = b$.
