Gaussian elimination definition math

WebApr 6, 2024 · The Gaussian elimination rules are the same as the rules for the three basic row operations, in other words, you can algebraically act on a matrix's rows in the following three ways: Interchanging two rows, for example, R2 ↔ R3. Multiplying a row by a constant, for example, R1 → kR1 where k is some nonzero number. WebGaussian elimination In linear algebra, Gaussian elimination (also known as row reduction) is an algorithm for solving systems of linear equations. It is usually ... Definitions and example of algorithm. Another point of view, which turns out to be very useful to analyze the algorithm, is that row reduction produces a matrix decomposition of ...
