![]() This involves maximizing or minimizing a linear objective function subject to linear constraints. Linear programming: Gaussian elimination can be used to solve linear programming problems. This is important in many fields, such as physics and engineering, where eigenvalues and eigenvectors are used to study the behavior of physical systems. This is useful in many applications, such as cryptography and optimization problems.Įigenvalues and eigenvectors: The Gaussian elimination method can be used to compute the eigenvalues and eigenvectors of a matrix. Inverse matrix: The inverse matrix of a matrix can be computed using Gaussian elimination. This is particularly useful in engineering and science applications, where linear equations are used to model physical systems. Solving systems of linear equations: The Gaussian elimination method is commonly used to solve systems of linear equations. Here are some of the applications of the Gaussian elimination method: It is important to note that if a pivot element is zero, you must interchange that row with another row below it that has a non-zero element in the same column before proceeding with the elimination process.įollowing these steps will allow you to solve systems of linear equations using Gaussian elimination. Substitute that value into the second-to-last row and solve for the corresponding variable, and so on until all variables have been solved for. Start with the last row and solve for the variable corresponding to the pivot element. Solve the system by back-substitution.Move to the next row and repeat steps 2 and 3 until the matrix is in upper triangular form.This is done by subtracting multiples of the first row from the subsequent rows. Use elementary row operations to make all the elements below the pivot in the same column equal to zero.Choose a pivot element, which is the first non-zero element in the first row.Write the augmented matrix of the system, which consists of the coefficients and the constants of the equations.To perform Gaussian elimination on a system of linear equations, follow these steps:
