MathPad Matrix Calculator is a simple, low cost utility for manipulating matrices of real numbers. It is as easy to use as a pocket calculator, but can perform most standard matrix operations for matrices. Matrix Calculator is aimed at teachers preparing coursework, students, or anyone who needs to work practically with matrices, simultaneous equations, etc.
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
curve fitting, analyzing differential equations, statistical processes, and even physical phenomena.
