3 Matrix Algebra Operations

Matrix algebra defines a set of operations that may be performed on
matrices. These operations include addition, subtraction,
multiplication, inversion (multiplication by the inverse is similar to
division) and transposition. We may separate the operations into two
mutually exclusive categories: *unary* and *binary*. Unary
operations are performed on a single matrix, and binary operations
combine two matrices to obtain a single matrix result. Binary
operations will be described first.
