High-precision calculation is an algorithm for programming design. Due to the word length limits of the central processing unit, for example, in a 32-bit CPU, an integer can only take a maximum value of 4,294,967,295 (=2^32-1). Therefore, in out-of-range numerical calculations, simulation methods are often required. Typically, the method of separating characters is used to … Read more
MATLAB is an essential and convenient tool in scientific and engineering research, and it is a skill that many graduate students must master before entering school. This article will help you quickly get started with MATLAB through three main sections. Basic Knowledge of MATLAB 1-1.

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

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
