ABSTRACT
This research work focuses on the application of matrix in solutions of some physical problems in science and engineering which arise in every human endeavor. This project work attempt to present some physical problems from the selected field (aspect) mentioned, so as to find the solution of the problems. The problems include; using matrice in the process of encrypting and decrypting data in this information age, solving electric circuit problem, balancing a complex chemical equation which is a difficult task for student offering chemistry, modeling of traffic flow to aid free flow, solving problem of forces acting on a truss, and modeling of electric network.
