In fact, this is the idea of Gaussian elimination--addition and subtraction of the yuan into the elimination of the YuanOf course, the Gaussian elimination is to become a ' Thief King ' algorithm (to be able to solve other general equations), of course, there must be a general method to carry out this step.First we apply a thing called a matrix, we take out the coefficients of each variable in the equation set to become the coefficients
Solution of a linear equation group:With the introduction of the general solution of the three equations of matrix equation, linear equation group and vector equation, we can express a linear equations in a relatively simple way. The following form is available:Ax = b. Where A is a matrix of M x n, corresponding to the coefficient matrix of a linear equation group, and X is a vector of r^n, the n unknown am

development of continuum mechanics, i.e., elasticity and fluid mechanics, and heat transfer, partial differential equations have also developed rapidly. The characteristics of the two disciplines in the development of mathematics and mechanics can not be reflected in the characteristics of the representative figures of the two disciplines. We can see that the most famous mathematicians in history are also the most famous mechanics at the same time. 1

Gaussian elimination method (transpose) Gaussian elimination method is an algorithm in linear algebra. It can be used to solve linear equations, obtain the rank of the matrix, and obtain the inverse matrix of the reversible matrix. The principle of Gaussian elimination method is: if the augmented matrix is converted into an Elementary Line Transformation, AX = B and CX = D are the same equations. Therefore,
condition for the color mixing mode. The gray scale ratio must be ensured. If the two are in conflict, do not consider the color proportion (for example, the gray scale of a pixel is 0 or 255 ). According to this idea, I gave up the HSB method for synthesis, and used the method for solving the equation according to the above two conditions to achieve color mixing. To do this, you can list the following equality relationships:

2: Mid-min = B

Fang zhouzi: opposite truth of the last big grievance in the history of mathematics
In the history of mathematics, this famous great grievance many people have heard from their teachers when they learn to solve equations in middle school. The story tells us that the Italian mathematician Talya in the Renaissance discovered the solution of the cubic equation, which is secret and unknown. A swindlers called the card dealer lied to the hacker about the s

Solving equations with Newton's methodNewton's method is an iterative algorithm for solving equations, and it can be used to solve the equations. The idea is to approximate the original equation by using the linear part of the equation (especially the nonlinear equation). Without losing its generalit
, two straight lines corresponding to the equation to solve. The equations of parallel lines are: ax+by+c1z =0; ax+by+c2z =0 (C1≠C2);Why Hint: can be considered from the slope, because parallel lines slope the same);The two equations are solved. There are c2z= c1z=-(Ax+by), ∵c1≠c2∴z=0∴ax+by=0;So the infinity point is that form (x:y:0). Note that the usual point z≠0, Infinity Point z=0, so the Infinity line

According to the basic knowledge of solving equations in linear algebra, we should first judge whether the rank of the coefficient matrix is equal to the rank of the augmented matrix. If there is no solution, if there is a solution, according to the relationship between the rank and the number of unknown quantities, the judgment is the only solution or the infinite solution, and if it is infinitely many solutions, the general solution of the homogeneo

Let's just think about where the infinity point is. According to the knowledge in the previous section, we know that the Infinity Point is the intersection of two parallel lines. So, how do you find the intersection coordinates of two lines? This is the knowledge of junior high school, is the two stra

Iteration Method is a common algorithm design method used to obtain the approximate root of equations or equations. Set the equation to f (x) = 0, use a mathematical method to export the equivalent form X = g (x), and then follow these steps:
