1.1 Introduction
Guassian elimination is the standard method for solving linear equations. As it is a ubiquitous algorithm and plays a fundamental role in scientific computation. Guassian elimination is a tool for obtaining the solution of equations, to compute the determinant, for deducing rank of coefficient matrix. However Guassian Elimination depends more on matrix analysis and computation it emphasis on block pivoting, methods of iteration and a means to improve the computed solution quality. It involves two stages forward and backward stage. Forward stage: Unknowns are eliminated in this stage by manipulation of equations and constitute an echelon form. Backward stage: it is related with back substitution process on the reduced upper triangular method resulting in a solution of equation.
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the Aim and Objectives of the study. Others are Significance of the study, Scope of work, Limitations of the Study and Definition of technical terms.
