* Matrix interface, dense and sparse (band or irregular) matrix encapsulation
* classes, LU, QR, Cholesky, SVD and eigen decompositions, etc. A matrix
* is a rectangular array of numbers, symbols, or expressions. The individual
* items in a matrix are called its elements or entries.
*
* One of most important matrix operations is the matrix vector
* multiplication, which is the only operation needed in many iterative matrix
* algorithms, e.g. biconjugate gradient method for solving linear equations and
* power iteration and Lanczos algorithm for eigen decomposition, which are
* usually very efficient for very large and sparse matrices.
