Introduction to Basic Knowledge 1. Basic Knowledge of MATLAB 1-1. Basic Operations and Functions In MATLAB, to perform basic mathematical operations, simply type the expression directly after the prompt (>>), and press Enter. For example: >> (5*2+1.3-0.8)*10/25 ans = 4.2000 MATLAB will store the result directly in a variable called ans, representing the answer after … Read more
MATLAB, which stands for Matrix Laboratory, is a mathematical tool software produced by MathWorks. The first version was released in 1984. MATLAB consists of two parts: the underlying MATLAB programming language and the upper-level toolbox modules. It features matrix operations, algorithm development, data visualization, data analysis, and supports creating user interfaces as well as calling … Read more
First Session Overview Common mathematical software includes Maple, Mathematica, Matlab and others; common large statistical software includes SAS, SPSS and others. Today, we will briefly introduce some Matlab functions, application areas, and its development history.Matlab has five general functions: numerical computation (Numeric), symbolic computation (Symbolic) (When requesting Matlab to perform symbolic computation, it requests Maple … Read more

MATLAB stands for Matrix Laboratory, which is an environment based on matrix operations. All data in MATLAB is stored in the form of matrices or multidimensional arrays. Vectors and scalars are two special forms of matrices. A vector refers to a matrix that is either a single row or a single column, and it is … Read more
Operators MATLAB has two different types of operators. Matrix operations are defined by the rules of linear algebra, while array operations can be performed element-wise and can be used for multidimensional arrays. The dot (.) character is used to distinguish array operations from matrix operations. For example, A*B represents traditional matrix multiplication, while A.*B represents … Read more
M-Files M-Files in MATLAB can be simple source files that execute a series of MATLAB statements or functions that receive inputs from variables and produce one or more outputs. This article focuses on M-File functions. These functions extend the capabilities of MATLAB and IPT to access specific user-defined applications. M-Files are created using a text … Read more
Author｜Liao Fan Chun Qiu Source｜Zhihu When it comes to machine learning, everyone thinks of Python. Indeed, Python offers a wealth of machine learning libraries, such as sklearn, pytorch, tensorflow, etc. Many C++ libraries also provide Python interfaces, like dlib, which makes it very convenient to use. Although Matlab is not as open as Python, it … Read more
