This unit introduces the theory and application of mathematical structures known as matrices. With the advent of computers matrices have become widely used in the mathematical modelling of practical real-world problems in computing, engineering and business where, for example, there is a need to analyse large data sets. Applications of matrices occur: • in all areas of science to solve (large) systems of equations. • in computer graphics to project three dimensional images onto two dimensional screens and apply transformations to rotate and move these screen objects. • in cryptography to encode messages, computer files, PIN numbers, etc. • in business to formulate and solve linear programming problems to optimise resources subject to a set of constraints.
