. . , xn) \u00b7 (y1, y2, . . . , yn) = Pn i=1 xiyi, and the norm of a vector x is de\ufb01ned as \u2225x\u2225= \u221ax \u00b7 x. Two vectors x, y are orthogonal if x \u00b7 y = 0. 7.2 Gaussian Elimination Gaussian Elimination is a historic algorithm, just like Euclid\u2019s algorithm (Section 1.1.3). It was \ufb01rst proposed by Isaac Newton ([Gravesande (1752)]), and later re\ufb01ned by Carl Friedrich Gauss.<\/p>\n

We say that a matrix is in row-echelon form if it satis\ufb01es the following two conditions: (i) if there are non-zero rows, the \ufb01rst non-zero entry of such rows is 1, (the pivot), and (ii) the \ufb01rst non- zero entry of row i + 1 is to the right of the \ufb01rst non-zero entry of row i.<\/p>\n

In short, a matrix is in row-echelon form if it looks as follows: \uf8ee \uf8ef\uf8ef\uf8ef\uf8ef\uf8ef\uf8ef\uf8ef\uf8ef\uf8ef\uf8f0 \u2217. . . \u2217 \u2217 \u2217. . . \u2217 \u2217 \u2217. . . \u2217 \u2217 \u2217. . . \u2217 \u2217 \u2217. . . \u2217 \u2217 … \u2217. . . \u2217 \u2217 . . . … … … \uf8f9 \uf8fa\uf8fa\uf8fa\uf8fa\uf8fa\uf8fa\uf8fa\uf8fa\uf8fa\uf8fb (7.1) where the \u2217\u2019s indicate arbitrary entries. We de\ufb01ne the function Gaussian Elimination, GE : Mn\u00d7m \u2212\u2192 Mn\u00d7n, to be the function which when given an n \u00d7 m matrix A as input, it outputs an n \u00d7 n matrix GE(A), with the property that GE(A)A is in row-echelon form.<\/p>\n

We call this property the correctness condition of GE. We show how to compute GE(A), given A. The idea is, of course, that GE(A) is equal to a product of elementary matrices which bring A to row-echelon form. We start by de\ufb01ning elementary matrices. Let Tij be a matrix with zeros everywhere except in the (i, j)th position, where it has a 1.<\/p>\n

Charles Dickens [Dickens (1854)], pg. 7 This book is a short introduction to algorithms, which are the meth- ods whereby we assign intellectual work to machines. Given a com- putational problem, an algorithm is a procedure to solve it; this procedure is usually implemented in a programming language, such as Python, to be run on a computer. We present two intertwined concepts related to algorithms: design technique, such as Greedy or Dynamic Programming; and analysis, such as performance or cor- rectness.<\/p>\n<\/blockquote>\n
