Euclidean algorithm is used to solve a set of X, Y, in known a, b to satisfy the Bézout equation: ax+by = gcd (A, B) =d (the solution must exist, according to the correlation theorem in number theory). Extended Euclidean is commonly used in solving linear equations and equations. Proof: (Interpretation of X and Y)1, obviously when B=0,GCD (A, b) =a. At this time x=1,y=0;2,abvoid extend_gcd (intint int int.

The linear congruence equations are obtained by multiple linear congruence equations. The mathematical notation is the solution to the equation Ai*x≡bi (mod m) (1≤i≤n).The complete works of the solution must be written in the form of X≡b (mod m), so we can solve all the linear congruence equations in turn.Because X≡B1 (mod M1), so the x is written in x=b1+m1*t an

Hair for several days compiled a solution to a linear equation group of small procedures, can be the first actual combat on the defeat and return. After half a day of debugging, still can not find a way to correct. Because it's not an algorithmic problem, it's because you don't understand the way the compiler handles floating-point functions. Clearly d=0 square matrix is not equal to 0, tracking debugging found that the calculation process procedures to the data to deal with, resulting in the en

The elementary transformation of the Matrix one. Mathematical concepts The nature of an equivalence relationship: (i) reflexive a~a; (ii) If the symmetry of  is a~b, then b~a; (iii) If the transitivity is A~b, the b~c is a~c; Two. focus, difficulty analysis The focus of this section is to use matrix Elementary transformations to transform matrices into row (column) ladder-shaped matrices, minimalist matrices, and standard-form matrices. Row (column) step-form matrices are essential for the ran

I've never learned linear algebra, but many of these algorithms are related to matrices, so we just have to learn to bite the bullet.Recently I think I can write a linear equation set of procedures? Then thought of such a method, temporarily can only calculate 3 yuan, arbitrary element of the next continue to think. There are too many hard coded, I hope interested readers can give some suggestions to modify! Copy Code code as follows: #include "stdafx.h"//vs2010 need #include "stdi

Previous postThe 0 spaces of ax=0 and matrix A are described.here we discuss the solution of AX=B and the column space of Matrix A. Ax=0 is definitely solvable, because the total presence of X is a full 0 vector. Make the equations set up. And ax=b is not necessarily a solution. We need to determine the Gaussian elimination element. We also use the previous article, which describes the solution of Ax=0, to illustrate:We can get the augmented matrix of
