This chapter discusses several numerical schemes for solving a system of equations which can be written in a compact form by using a matrix﹙ector notation. It looks over some algorithms to solve a system of linear equations, namely Gauss(ian) elimination, partial pivoting, and Gauss㎎ordan ...
We have seen how to write a system of equations with an augmented matrix, and then how to use row operations and back-substitution to obtain row-echelon form. Now, we will take row-echelon form a step farther to solve a 3 by 3 system of linear equations. The general ide...
