FAQs - Gaussian Elimination Calculator​

The use of a particular equation to eliminate a variable from other equations is called a pivot, and a rule we use to settle on which equation to use is called a pivoting strategy. The resulting modified algorithm with partial pivoting is called Gaussian elimination.

The Naive Gaussian Elimination is a simple and systematic algorithm for solving linear systems of equations.
