/*stern-brocot algebra System Stern-brocot tree is a wonderful way to generate all non-negative, minimal fraction m/n. The basic approach is to start with the two fractions (0/1, 1/0) and repeat as needed: Insert (M+M1) between adjacent fractions m/n and m1/n1 (N+N1) For example, you can see it as an infinitely extended two-fork Tree 0 1 1---------1 1 0/\/\ 1 2------2 1/\/\/\/1 2 3 3------------3 3 2 1 ........

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 linear equation whether there is a solution and the number of the solution

This blends the benefits of multiple architectures. Data PartitioningThe purpose of data partitioning is to allow the database to read and write data in parallel, maximizing the potential for I/O . Common partitioning algorithms are:round-robin, range index, hash.parallelism of relational operationspropert

Prepare to write an article about Singular Value DecompositionArticleIt suddenly found that it needed a lot of linear algebra knowledge. Therefore, we will first introduce the basic concepts and operations of linear algebra to help readers understand Singular Value Decomposition. 1. Basic Concepts A matrix is a number composed of several rows and columns, which is equivalent to a table. In particular, if

The two theorems are very simple, obviously, and seem to be the basic arithmetic in proving matrix algebra. But it lays a theoretical foundation for understanding Matrix-vector Product ax with "linear transformation".Combining the properties of the matrix and vector product AX we discussed before, we can introduce a linear transformation.Because the properties of the product of matrix A and vector x are closely related to the definition of linear tran

A very important concept in linear algebra is the vector space r^n, which will focus on a series of properties of vector space.A vector space is a non-empty set v consisting of some vector elements, which needs to satisfy the following axioms:The subspace H of the vector space V needs to meet the following three conditions:The two theorems are in the elaboration of how to form subspace, and its proof simply proves that the constructed subspace satisfi

Linear transformations:As we mentioned earlier, when we discuss the matrix equation ax = b and the vector equation X1a1+x2a2+x3a3+...+xnan = b, we have said that this will echo the rules of matrix multiplication. But here we first introduce a concept of transition-the linear transformation.To investigate the matrix equation ax = B,a is the n x m matrix, X is the r^n vector, by the rule we defined earlier, B must be the r^m vector. We abstract this process, from the point of view of set theory or

generally, the polynomial that satisfies \ (f (\mathscr{a}) =0\) is called \ (\mathscr{a}\) of the 0 polynomial , where the least number of first polynomial is called the minimum polynomial of \ (\mathscr{a}\), Record as \ (d (\LAMBDA) \). These definitions are also established for matrices, and it is clear that the least polynomial is also a invariant of similar transformations. Similar to the analysis in abstract algebra, it is easy to know that th

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. Mastery can be.3) Inverse of the matrix, from the basic method (cofactor-type → algebraic cof

of "description".For a linear transformation, as long as you select a set of bases, you can find a matrix to describe the linear transformation. To change a group of bases, you get a different matrix. All of these matrices are a description of the same linear transformation, but they are not linear transformations themselves.Similarly, given two matrices, how do you know if the two matrices are the same linear transformation described? If it is the same linear transformation of the different ma
