Gaussian elimination[¦gau̇·sē·ən ə‚lim·ə′nā·shən] (mathematics) A method of solving a system of n linear equations in n unknowns, in which there are first n- 1 steps, the m th step of which consists of subtracting a multiple of the m th equation from ea...
At step i of Gaussian elimination, the pivot element is aii. To eliminate each element aji, i + 1 ≤ j≤ n, multiply row i by aji /aii and subtract from row j. These multipliers should not be large or precision can be lost. Find the largest of the elements {|aii|,|ai+1,i|,...
by Marco Taboga, PhDGaussian elimination is an algorithm that allows us to transform a system of linear equations into an equivalent system (i.e., a system having the same solutions as the original one) in row echelon form. Elementary row operations are performed on the system until the ...

Gaussian elimination uses valid row operations on a matrix until it is in reduced row echelon form. Learn about systems of linear equations,...
Gaussian Elimination is a process conducted on matrices aimed to put a matrix into echelon form, which helps enormously to solving matrix equations
Gaussian elimination calculator. This step-by-step online calculator will help you understand how to solve systems of linear equations using Gauss-Jordan Elimination
Interactive Illustration 5.9: Typical example of Gaussian elimination. The first step is simply to copy the first equation, which can be seen when clicking/pressing Forward. Interactive Illustration 5.9: We start by working on the bottom equation. We now want to eliminate the first variable, x...
(The methodology for solving these larger systems of equations is an extension of the two-variable solving-by-addition method, so make sure you know this method well and can consistently use it correctly.)Though the method of solution is based on addition/elimination, trying to do actual the ...
