multiplied by \ (i,a,a^2,\cdots\) and added, resulting in a \ (0=f (A) \), which is as if the Matrix \ (a\) into the equation (1). But this kind of generation is generally very difficult to set up, it is due to the special form of the characteristic matrix, we can take this interesting nature as a conclusion,\[(\lambda i-a) g (\LAMBDA) = (\lambda i-a) (\lambda^mb_m+\lambda^{m-1}b_{m-1}+\cdots+b_0) =\lambda^nc_n+\lambda^{n-1} C_{n-1}+\cdots+c_0=f (\LA

unknown, we call this equation incompatible if we know that the equals sign will never be true. For incompatible equations, an x can be obtained to make:To make the distance between B ' and B nearest, the method that requires such x is the solution equation:If both A and B are vectors with only one column, the equation can be simplified to a vector inner product, i.e.:By this formula to calculate the data

The first self-taught Tongji 5 version of the linear algebra, from the beginning to look, also a little puzzled, suddenly there are many determinant appear, in fact, the definition of the real does not understand.Refer to the Li Shangzhi teacher's linear Algebra 2 video and make some notes to enhance understanding.1. T

Chapter One solution of linear equation Group Algebra originates from Solution equations (algebraic equations) One dollar, one yuan two times, one yuan three times, one yuan four times have to find the root formula (through the coefficients of the finite times add, subtract, multiply, divide, the powers, the root to get the solution), more tha

This week has focused on a number of topics, including:1) from the perceptual knowledge of what is linear algebra, and from the ideological realization that linear algebra is useful.2) Simple understanding of the addition, subtraction, multiplication of the matrix. These are some of the rules that people prescribe. Mas

To pick up the flowers Don't forget beginner's mind Apply 've seen Bit by bit Linear algebra is a compulsory course in the University of Science, I am ashamed to say that I have not learned, throughout the semester all the classes I was thinking about one thing: this thing is very complex, what can be used to do? Think back to the math lesson I had since I was a kid:Primary school is su

Chapter 2 Solving Linear equations2.1 Vectors and Linear equationsthe core problem of linear algebra : Solving the equation system. ------------"but slope are important in calculus and this islinear algebra".a*x=b two kinds of vie

Make a mark and have time to summarize the knowledge of the linear algebra obtained in the 10-day course to finish a book.1. Determinant: The value can be evaluated2, Matrix: There is a corresponding determinant, the matrix itself can not calculate a value, but can be by the equivalent determinant of the value of the matrix and the adjoint matrix, whether reversible, is also a

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 sol

assume that the line expression is as follows:Then calculate the error function:The error function e is obtained by the deviation of the coefficient, a, a, and the 0:The value of the coefficients, a, a, a, and a linear expression is obtained by the above formula:The curves obtained by the least squares are as follows:Linear algebraic approach to least squares: Similarly, the expression of a fitted line is set to:The purpose of fitting is to make the

Mastering linear algebra in 10 days: astoundin Translator: mapleflying Recently, my friend Scott Young made an amazing feat: within a year, he completed all 33 of the legendary mit computer science curriculum, from Linear Algebra to Computational Theory. The most important thing is that he is self-taught. He watches

The previous articles on linear algebra are all explained in terms of mathematics. This article will be a different angle to explain the problem.The tutor often tells me that everything has to think about its physical or practical significance, through the phenomenon to see the essence, so that can be more profound understanding, so you can see what the actual use of li
