```Introduction to linear and multilinear algebra and matrix theory. As presented to
engineers and as the subject of much numerical analysis, this subject is Matrix Theory.
To an algebraist or geometer, it is the theory of Vector Spaces. Linear algebra, sometimes
disguised as matrix theory, considers sets and functions which preserve linear structure.
In practice this includes a very wide portion of mathematics; thus linear algebra includes
axiomatic treatments, computational matters, algebraic structures, and even parts of
geometry; moreover, it provides tools used for analyzing differential equations, statistical
processes, and even physical phenomena.
The College Mathematics Journal is produced by the Mathematical Association of
America and contains article accessible to college students.. Each of the following is an
article on linear algebra selected from The College Mathematics Journal. These can
potentially be used as a basis for student projects in linear algebra.
