The editor will share with you what matlab means. I hope you will get something after reading this article. Let's discuss it together.

Introduction to matlab

MATLAB is a commercial mathematics software produced by American MathWorks Company. It is an advanced technical computing language and interactive environment for algorithm development, data visualization, data analysis and numerical calculation. It mainly includes two parts: MATLAB and Simulink.

MATLAB is a combination of the word matrix&laboratory, meaning matrix factory (matrix laboratory). It is a high-tech computing environment mainly facing scientific computing, visualization and interactive programming, which is released by mathworks Company of the United States. It integrates many powerful functions, such as numerical analysis, matrix calculation, scientific data visualization and nonlinear dynamic system modeling and simulation, into an easy-to-use window environment. It provides a comprehensive solution for scientific research, engineering design and many scientific fields where effective numerical calculation must be carried out. And to a large extent, it gets rid of the editing mode of traditional non-interactive programming languages (such as C, Fortran), and represents the advanced level of international scientific computing software.

The basic data unit of MATLAB is matrix, and its instruction expression is very similar to the form commonly used in mathematics and engineering, so it is much simpler to solve problems with MATLAB than to accomplish the same thing with Corey FORTRAN and other languages, and MATLAB also absorbs the advantages of software such as Maple, making MATLAB a powerful mathematical software. The new version also adds support for Cpene FORTRAN Category recording Java.

Programming environment

MATLAB consists of a series of tools. These tools make it easy for users to use MATLAB functions and files, many of which use a graphical user interface. Includes MATLAB desktop and command windows, history command windows, editors and debuggers, path search, and browsers for users to browse help, workspaces, and files. With the commercialization of MATLAB and the continuous upgrading of the software itself, the user interface of MATLAB is becoming more and more refined, closer to the standard interface of Windows, stronger human-computer interaction and simpler operation. And the new version of MATLAB provides a complete online query and help system, which greatly facilitates the use of users. The simple programming environment provides a relatively complete debugging system, the program can be run directly without compilation, and can report errors and analyze the causes of errors in time.

Simple and easy to use

Matlab is an advanced matrix / array language, which contains control statements, functions, data structures, input and output, and object-oriented programming features. You can synchronize input statements with execution commands in the command window, or you can write a large and complex application (M file) and then run it together. The new version of MATLAB is based on the most popular C++ language, so its grammatical features are very similar to C++ language, and are simpler and more in line with the format in which scientists and technicians write mathematical expressions. To make it more convenient for non-computer professionals to use. Moreover, this language has good portability and strong extensibility, which is an important reason why MATLAB can go deep into various fields of scientific research and engineering computing.

Powerful processing

MATLAB is a collection containing a large number of computational algorithms. It has more than 600 mathematical operation functions to be used in the project, which can easily realize all kinds of calculation functions that users need. The algorithms used in the function are the latest research results in scientific research and engineering calculation, and have gone through a variety of optimization and fault-tolerant processing. In general, it can be used instead of underlying programming languages, such as C and C++. When the calculation requirements are the same, the programming effort of using MATLAB will be greatly reduced. These function sets of MATLAB range from the simplest and most basic functions to complex functions such as matrices, eigenvectors, and fast Fourier transforms. The problems that can be solved by function include matrix operation, solution of linear equations, solution of group of differential equations and partial differential equations, symbolic operation, Fourier transform and statistical analysis of data, optimization problems in engineering, sparse matrix operation, complex operation, trigonometric function and other elementary mathematical operations, multi-dimensional array operation and modeling dynamic simulation, etc.

Graphic processing

MATLAB has a convenient data visualization function since it came into being, so that the vectors and matrices can be represented graphically, and the graphics can be marked and printed. High-level mapping includes 2D and 3D visualization, image processing, animation, and expression mapping. It can be used in scientific calculation and engineering drawing. The new version of MATLAB makes a great improvement on the whole graphics processing function, which not only makes it more perfect in the functions that general data visualization software has, such as the drawing and processing of two-dimensional curves and three-dimensional surfaces, but also shows excellent processing ability for some functions that other software does not have (such as lighting processing, chromaticity processing and the performance of four-dimensional data, etc.). At the same time, for some special visualization requirements, such as graphic dialogue, MATLAB also has corresponding functions to ensure the requirements of different levels of users. In addition, the new version of MATLAB also focuses on the production of graphical user interface (GUI) has made a great improvement, users with special requirements in this area can also be met.

Module tool

MATLAB has developed powerful module sets and toolkits for many specialized areas. In general, they are developed by domain-specific experts, and users can use toolkits to learn, apply, and evaluate different methods directly without having to write their own code. Domain Such as data acquisition, database interface, probability and statistics, spline fitting, optimization algorithm, partial differential equation solving, neural network, wavelet analysis, signal processing, image processing, system identification, control system design, LMI control, robust control, model prediction, fuzzy logic, financial analysis, map tools, nonlinear control design, real-time rapid prototyping and semi-physical simulation, embedded system development, fixed-point simulation, DSP and communication, power system simulation, etc. All have their own place in the Toolbox family.

Program interface

The new version of MATLAB can automatically convert its MATLAB programs into C and C++ code that runs independently of MATLAB by using the MATLAB compiler and the CumberCandle + math and graphics libraries. Allows users to write C or C++ language programs that can interact with MATLAB. In addition, MATLAB web services allow their own MATLAB math and graphics programs to be used in Web applications. One of the important features of MATLAB is that it has a set of program extension system and a group of special application subroutines called toolboxes. The toolbox is a subroutine library of MATLAB functions. Each toolbox is customized for a certain discipline and application, including signal processing, control system, neural network, fuzzy logic, wavelet analysis and system simulation.

Software development

In the development environment, it makes it easier for users to control multiple files and graphics windows; supports function nesting and conditional interruptions in programming; in graphics, it has more powerful graphics annotation and processing functions, including sexual connection notes; in input and output, you can connect directly to Excel and HDF5.
