QR factorization can be used with both square and rectangular matrices. The QR factorization technique factors the input matrix A as the product of two matrices, such that A = QR, where R is an upper triangular matrix. The problem can be expressed in narrative algebraic form. This paper adopts the systems of linear equations. The equations in the system can be linear or non-linear. In solving a system of equations, we try to find values for each of the unknowns that will satisfy every equation in the system. A system of equations is a collection of two or more equations with the same set of unknowns. Solutions of Systems of Linear Equations. Yet, one has to take care that such software can also be used for real system control. Virtual laboratories typically originate from computation and simulation software such as Matlab or LabVIEW. This background concurs with Virtual laboratories, Solutions of Systems of Linear Equations (The QR factorization technique and LU factorization technique), and LU factorization technique. The LU is preferred to Matlab because LABVIEW is a graphical user interface (GUI) and it can easily be understood by the students.

It is for those who use the numerical linear system. The main purpose of this paper is to help unspecialized people in the computer science. Using the LabVIEW, program has been designed and tested, and the application of the solution of a system of linear equations by 1) QR Method A is, 2) QR Method A is, and 3) QR Method A is and Solving Systems of Equations LU-Factorization Method. The linear system of equations using LU and QR methods is used because the sample students study a course of the linear system of equations solved by LU and QR methods. This paper will design and develop Interactive Virtual modules (VIs) for studying 1) QR Factorization, 2) LU Factorization. Factorization methods can be used to solve many matrix problems, such as solving linear system of equations, inverting a matrix, and finding the determinant of a matrix. The QR factorization methods can handle both square and rectangular matrices. The LU factorization methods are available only for square matrixes. The most commonly used factorization methods are LU and QR.

A linear system of equations can be transformed into a system whose solution is simpler to compute by factoring the input matrix into the multiplication of several simpler matrices. Of the available packages, LabVIEW is the most widely used in GUI. There are several numerical computation packages that serve as educational tools and are also available for commercial use.
