Gauss-Jordan Row Reduced Echelon Method

Sisema de Ecuaciones - Metodo de gauss

In the practice of engineering and science it is often the need to solve a system of linear equations. These systems appear in a variety of problems, either as the complete solution to a problem or at least part of it. Given this increased frequency is required to efficiently solve them through the iterative and direct methods.


Iterative methods and directs for systems of linear equations
The matrices are used in the numerical computation in solving systems of linear equations, differential equations and partial derivatives. Besides its usefulness for the study of systems of linear equations, matrices appear naturally in geometry, statistics, economics, computer science, physics, etc ...

The use of matrices (arrays) is now an essential part dn programming languages, since most data are entered into the computers at the tables arranged in rows and columns: spreadsheets, databases, .

Roots of equations

This chapter deals with roots of equations with methods that take advantage of the fact that a function in a typical change of sign in the vicinity of a root. The specific methods described on this point employ different strategies to systematically reduce the length of the interval and so converge to the correct answer. There diferenttes classes are methods including graphical methods, open and closed.

Numerical Approximation

Through this article you may have an orientation about what are the numerical approximations, and the great importance when you want to give more precise numerical data, so it know the errors that are obtained when they are doing various calculations.
