Inverse Method for Order n Matrix

Abstract

The power of matrix algebra was seen not only in applied mathematics, applied sciences, engineering but also in economics, sociology, modern psychology and industrial management (i.e., system of linear equation, cryptography, optics, signal processing, image processing, graph theory, Machine Learning, Data Science etc.). In practice the matrix inverse methods is suitable only for non-singular small system because the higher the size of the system the more difficult finding the inverse of the system even with the help of software/application. With experience we were able to find the inverse of order 4, 5, … , n matrix with ease and also verified the method by computing .
