The
evolution of concept of matrices is the result of an attempt to obtain compact and
simple methods of solving system of linear equations Matrices are not only used as a
representation of the coefficients in system of linear equations, but utility of matrices
far exceeds that use Matrix notation and operations are used in electronic spreadsheet
programs for personal computer, which in turn is used in different areas of business
and science like budgeting, sales projection, cost estimation, analysing the results of an
experiment etc Also, many physical operations such as magnification, rotation and
reflection through a plane can be represented mathematically by matrices
