Section 5 of Matrix In this section, we will introduce a commonly used method for processing matrices with higher levels, that is, matrix blocks. sometimes, we regard a large matrix as composed of small matrices, just as the matrix is composed of

1. Vector TransformationVector transformation is a function from one vector space to another (or the same) vector space. In the vector world, this function is called transformation, which is usually represented by the symbol t. 2. linear

This section mainly reviews some simple knowledge about linear algebra.Matrix and vector Matrix Number of $ m \ times N $ A _ {IJ} (I = ,..., m; j = 1, 2 ,..., n) $ the number table of $ M $ row $ N $ column, which is called the matrix of $ M $ row $

This time, the core content is entered, and feature values and feature vectors are calculated. I believe that with the foundation of the first two articles, you will not feel any obstacles. Enter the subject 1. Calculate the feature value For the

Exercise: 7. rewrite theorem 1.4.10 to a more general language. The first sentence is: "set $ F $ to the full homomorphic of the group $ g _ {1} $ to $ g _ {2} $, and $ H Similar to this theorem, we provide the following solutions: (1) $ HN $ is

1. Linear Combination For n-dimensional vector groups {V1, V2, V3 ,..., VK}, if any real number C1, C2, C3 ,... CK, then the vector V' = C1 * V1 + C2 * V2 +... + ck * VK is a linear combination of vector groups. a linear combination refers to a

In the previous article, we have defined the transpose matrix. The transpose matrix of A is recorded as T (A), and we know that det (A) = det (A transpose ). 1. Transpose of Matrix ProductMatrix A and B, with T (AB) = T (B) * t ().Matrix A1, a2...

Original: Click to open the link "Homogeneous coordinate representation" is one of the important means of computer graphics, it can be used to distinguish between vectors and points, and it is more easily used for affine (linear) geometric

AI indicates whether each node is a button, according to the case of each point equation Total n unknowns, n equations After the Gauss elimination, may appear the free element, the 2^s enumeration free element Choice, calculates the

section Fourth two and its standard form A. Mathematical Concepts 1. Two-time type A two-time homogeneous function called n variables is a two-time type. 2. Matrix form of two-times type 3. Rank of two-time type The rank =r of f (a). 4.

technology provides luxury computing power ). In such applications, the more "Dummies" the data collection method, the better (and such systems also need to be strong, such as being able to tolerate 10% of sensor loss or various kinds of noise and data defects ). This is the application of compression sensing. The theoretical basis is: if we only need 0.1 million parts to reconstruct the vast majority of images, why do we need to do all the 2 millio

curves were what people could see in space. the high dimension has a little fictional component, which people can imagine through mathematical thinking, but at that time people may not take them seriously. take them seriously and study them with the same degree of attentionThis idea is actually a product of the 20th century. similarly, there is no clear evidence that our pioneers in the 19th century have considered the increase in the number of functions. The research is not just a single but a

It is precisely because of these conclusions that are totally against common sense that the mathematics field once had a heated debate over whether to accept it for a long time.

work and hard work. Further questions: how to measure the teacher's degree of effort and teaching effect? You can also say that the score of a student can also be measured by the teacher. However, what is the actual proportion. Of course, this is not clear, and it cannot be clear. Because they are a whole. There are also ways for university administrators to evaluate their knowledge. Unfortunately, government decrees tend to become distorted as they move down from the top of the pyramid. For ex

Editor's note: If you want to machine learning, linear algebra must first, as for why, look at this article, certainly will be inspired. At the same time, the site recommends MIT Strang's linear Algebra Open class: Http://v.163.com/special/opencourse/daishu.html, while recommending his two textbooks (known as North America's most popular): "Introduction to Linear Algebr
