Row swapping is a fundamental operation in matrix manipulation used to interchange two rows of a matrix, often employed in algorithms like Gaussian elimination to simplify solving linear equations. It is crucial for numerical stability and accuracy, especially when dealing with pivot elements that are zero or near-zero.

Gaussian Elimination is a method for solving systems of linear equations by transforming the system's augmented matrix into a row-echelon form, from which the solutions can be easily obtained using back substitution. This technique is fundamental in linear algebra and is widely used in various fields, including engineering and computer science, for its straightforward computational approach.

Numerical stability refers to how an algorithm's errors are amplified during computations, especially when dealing with floating-point arithmetic. Ensuring numerical stability is crucial for maintaining accuracy and reliability in computational results, particularly in iterative processes or when handling ill-conditioned problems.
