Matrices And Determinants
Matrices and determinants were discovered and developed in the 18th and 19th centuries. Initially, their development dealt with the transformation of geometric objects and the solution of systems of linear equations. Historically, the early emphasis was on the determinant, not the matrix. In the modern treatment of Linear Algebra, matrices are considered first.
Matrices provide a theoretically and practically useful way of approaching many types of problems including; Solutions of system of linear equations, Equilibrium of rigid bodies, Graph theory, Theory of games, Leontief economics model, Forest management, Computer graphics and Computed tomography, Genetics, Cryptography, Electrical networks, etc.
Matrices are a very important tool in expressing and discussing problems which arise from reallife issues. Matrices are applied in the study of electrical circuits, quantum mechanics and optics, in the calculation of battery power outputs and resistor conversion of electrical energy into another useful energy.
Matrices play a major role in the projection of threedimensional images into a twodimensional screen creating the realistic seeming motion. Matrices are used in calculating the gross domestic products in Economics which eventually helps in calculating the production of the goods efficiently.
Matrices are the base elements for robot movements. The movements of robots are programmed with the calculation of matrices row and columns. The inputs for controlling robots are given based on the calculations from matrices. Matrices are also used in many organizations by scientists for recording data of their experiment.
