Matlab2015b software functions

programming environment

Matlab2015b consists of a series of tools. These tools make it easy for users to use MATLAB functions and files, and many of them use graphical user interfaces. Includes MATLAB desktop and command window, historical command window, editor and debugger, path search, and browser for users to browse help, workspace, and files. With the commercialization of MATLAB and the continuous upgrading of the software itself, the user interface of MATLAB has become more and more refined, closer to the standard interface of Windows, with stronger human-computer interaction and simpler operation. Moreover, the new version of MATLAB provides a complete online query and help system, which greatly facilitates user use. The simple programming environment provides a relatively complete debugging system. The program can be run directly without compilation, and errors can be reported in a timely manner and the cause of the error can be analyzed.

Simple and easy to use

Matlab is a high-level matrix/array language that contains control statements, functions, data structures, input and output, and object-oriented programming features. Users can synchronize input statements and execution commands in the command window, or they can first write a larger and complex application (M file) and then run them together. The new version of MATLAB language is based on the most popular C++ language, so the syntax features are very similar to the C++ language, and it is simpler and more in line with the writing format of mathematical expressions by scientific and technical personnel. Make it more conducive to use by non-computer professional technical personnel. Moreover, this language is highly portable and highly scalable, which is also an important reason why MATLAB can penetrate into various fields of scientific research and engineering calculations.

Strong processing power

MATLAB is a collection of numerous computational algorithms. It has more than 600 mathematical operation functions used in projects, which can easily realize various calculation functions required by users. The algorithms used in the functions are the latest research results in scientific research and engineering calculations, and have undergone various optimization and fault-tolerant processing. In general, it can be used in place of low-level programming languages ​​such as C and C++. With the same computational requirements, the programming workload using MATLAB will be greatly reduced. These MATLAB function sets range from the simplest and most basic functions to complex functions such as matrices, eigenvectors, and fast Fourier transforms. The problems that functions can solve generally include matrix operations and the solution of linear equations, differential equations and partial differential equations, symbolic operations, Fourier transform and statistical analysis of data, optimization problems in engineering, sparse matrix operations, Various operations on complex numbers, trigonometric functions and other elementary mathematical operations, multi-dimensional array operations, and modeling and dynamic simulation, etc.

graphics processing

MATLAB has had convenient data visualization functions since its inception to graphically represent vectors and matrices, and the graphics can be annotated and printed. High-level graphics include two- and three-dimensional visualization, image processing, animation, and expression graphics. Can be used for scientific calculations and engineering drawings. The new version of MATLAB has greatly improved and perfected the entire graphics processing function, making it not only more complete in terms of functions that general data visualization software has (such as the drawing and processing of two-dimensional curves and three-dimensional surfaces, etc.), but also for For some functions that other software does not have (such as graphics lighting processing, chroma processing, and four-dimensional data representation, etc.), MATLAB also shows excellent processing capabilities. At the same time, MATLAB also has corresponding functions for some special visualization requirements, such as graphical dialogue, etc., to ensure different levels of user requirements. In addition, the new version of MATLAB also focuses on making great improvements in the production of graphical user interface (GUI), and users with special requirements in this regard can also be satisfied.

MATLAB has developed powerful module sets and toolboxes for many specialized fields. Generally, they are developed by experts in specific fields, and users can directly use the toolbox to learn, apply and evaluate different methods without writing code themselves. Fields such as data acquisition, database interface, probability statistics, spline fitting, optimization algorithm, partial differential equation solution, 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 communications, power system simulation, etc., are all in the Toolbox He has his own place in the family.

Program interface

The new version of MATLAB can use the MATLAB compiler and the C/C++ math library and graphics library to automatically convert your own MATLAB programs into C and C++ code that runs independently of MATLAB. Allows users to write C or C++ language programs that can interact with MATLAB. In addition, the MATLAB web server allows you to use your own MATLAB math and graphics programs in web applications. An important feature of MATLAB is a program extension system and a set 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, mainly including signal processing, control system, neural network, fuzzy logic, wavelet analysis and system simulation. application.

Application software development

In the development environment, it allows users to control multiple files and graphics windows more conveniently; in terms of programming, it supports function nesting, conditional interruption, etc.; in terms of graphics, it has more powerful graphics annotation and processing functions, including In terms of input and output, you can directly connect to Excel and HDF5.
