For a group of polynomial equations (in the Augmented Matrix, X [I, n + 1] represents the values of formulas, and X [I, j] represents the coefficients of the J items of the I equation, here, the Augmented Matrix may not necessarily be N, but may be less; opt indicates the operation rule ):
(X [1, 1] * A [1]) OPT (X [1, 2] * A [2]) opt... opt (X [1, N] * A [n]) = x [1, n + 1]
(X [2, 1] * A [1]) OPT (X [2, 2] * A [2]) opt... opt (X [2, N] * A [n]) = x [2, n + 1]

Self-taught a burst of Gauss extinction, feeling this thing listening to the advanced, in fact, is still very logical (logical). Below I will share my own understanding of the Gaussian elimination, hope can also help beginners understand the algorithm.First, we need to be clear: the purpose of Gaussian elimination is t

"Problem Analysis"The Gaussian elimination element is a linear base.The topic itself is not difficult, but two methods of maintaining a linear base have caused my thinking.

First, let's talk about Gaussian elimination: it refers to the process of converting the Augmented Matrix into an upper triangle matrix and then determining the solution. Assume that a * x = B. A is a matrix of N * m, X is the solution matrix of M * 1, and B is the coefficient matrix of N * 1. Then, the Augmented Matrix is a matrix of N * (m + 1.
There are three situations after

Steps:Where a is a n*n the coefficients of the square vectors x and b are the unknowns and the constant vectors respectively:The system may have 0, one, or infinitely multiple solutions, depending on the coefficients matrix A and vector B. There are many methods for solving linear systems, where a classical method-Gaussian elimination (https://zh.wikipedia.org/wiki/Gaus

"The main topic"There are n number or odd or even, now do m operations, each fetch part sum, tell you the number of operations selected and their parity. If the parity of all the numbers can be obtained by this m operation, the output can be answered at nth times, otherwise the output cannot be determined.IdeasIn order to solve the XOR equations, the Gaussian elimination element can not determine the minimu

People who have studied mathematics know that Gaussian elimination method is used to solve linear equations. The algorithm is very simple, but the process is very complicated, this is why I cannot find a free and correct Gaussian elimination method on the Internet. So I made up my mind to compile it myself.Gaussian
