P.V. Ubale, Comparison of Solution of 3x3 System of Linear Equation in Terms of Cost, BSMaSS Volume 4, The Bulletin of Society for Mathematical Services and Standards (Volume 4)
    The solution of a linear system is one of the most frequently performed calculations in computational mathematics. Many numerical methods are involved to solve the system of linear equations. There are two basic approaches elimination approaches and iterative approaches are used for the solution. In this paper we describe the comparison of two popular elimination procedure simple Gauss Elimination and Gauss Jordan elimination method on to the solution of 3x3 system of linear equation and find out the cost required to implement this procedures.
