WebThe row-swapping procedure outlined in (1.2.3-1), (1.2.3-6), (1.2.3-7) is known as a partial pivoting operation. For every new column in a Gaussian Elimination process, we 1st … Gaussian elimination is numerically stable for diagonally dominant or positive-definite matrices. For general matrices, Gaussian elimination is usually considered to be stable, when using partial pivoting, even though there are examples of stable matrices for which it is unstable. Generalizations See more In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of operations performed on the corresponding See more Historically, the first application of the row reduction method is for solving systems of linear equations.
