This is a classic and difficult stack problem Valley link ** Topic introduction ** Input format Output format Know the Chinese translation you can't understand: Matrix chain multiplication Title Description Suppose you have to evaluate an expression form, such as ABCDE, where A,B,C,D,E are matrices. Since matrix multiplication is a ...

1, Purpose and requirements: 1. Familiar with the theory and method of solving linear equations; 2. Be able to prepare column principal component elimination method, LU decomposition method, Jacobian and Gauss Seidel iterative Fard procedures; 3. Through practical calculation, we can further understand the advantages and disadvantages of var ...

Fitting, as the name suggests, is to find the mathematical relationship between data through the analysis of data. The deeper the understanding of the essence of this relationship, the higher the degree of fitting, and the clearer the relationship between data. Fitting includes linear fitting and nonlinear fitting (polynomial fitting). This pap ...

1, Introduction to particle swarm optimization 1 Introduction The group behavior of birds and fish in nature has always been the research interest of scientists. Biologist Craig Reynolds proposed a very influential bird swarm aggregation model in 19 eight 7. In his simulation, each individual follows: avoid collision with neighboring individua ...

Linear algebra and code implementation (I) vector background The Linear Algebra I studied in university is a little forgotten now, and I am not proficient in the code implementation; This column mainly reviews the basis of linear algebra and implements the code part; 1. Some basic concepts Essence: the basic expression of a group of numbers ...

1. Introduction 1 PCA 1.1 Data Dimension Reduction The methods of dimension reduction include principal component analysis (PCA), factor analysis (FA), and independent component analysis (ICA). Principal Component Analysis: Find a vector to minimize the sum of projections from each sample to that vector. Factor analysis: Independent component ...

1, Brief introduction of digital baseband signal waveform simulation This paper mainly studies the basic concept of digital signal baseband transmission, the transmission process of digital signal baseband transmission, and how to simulate and design digital baseband transmission system with MATLAB software. Firstly, this paper introduces the ...

1. Introduction to cellular automata Development of 1-cell automata The original cellular automata was proposed by Von Neumann in the 1950s to mimic the self-replication of biological cells.But it has not been taken seriously by the academia. It was only after John Horton Conway of the University of Cambridge designed a computer game called &q ...
