Introduction
What Is MATLAB?
MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Typical uses include:
MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. This allows you to solve many technical computing problems, especially those with matrix and vector formulations, in a fraction of the time it would take to write a program in a scalar noninteractive language such as C or Fortran.
The name MATLAB stands for matrix laboratory. MATLAB was originally written to provide easy access to matrix software developed by the LINPACK and EISPACK projects, which together represent the state-of-the-art in software for matrix computation.
MATLAB has evolved over a period of years with input from many users. In university environments, it is the standard instructional tool for introductory and advanced courses in mathematics, engineering, and science. In industry, MATLAB is the tool of choice for high-productivity research, development, and analysis.
MATLAB features a family of application-specific solutions called toolboxes. Very important to most users of MATLAB, toolboxes allow you to learn and apply specialized technology. Toolboxes are comprehensive collections of MATLAB functions (M-files) that extend the MATLAB environment to solve particular classes of problems. Areas in which toolboxes are available include signal processing, control systems, neural networks, fuzzy logic, wavelets, simulation, and many others.
The MATLAB System
The MATLAB system consists of five main parts:
The MATLAB language.
This is a high-level matrix/array language with control flow statements, functions, data structures, input/output, and object-oriented programming features. It allows both "programming in the small" to rapidly create quick and dirty throw-away programs, and "programming in the large" to create complete large and complex application programs.
The MATLAB working environment.
This is the set of tools and facilities that you work with as the MATLAB user or programmer. It includes facilities for managing the variables in your workspace and importing and exporting data. It also includes tools for developing, managing, debugging, and profiling M-files, MATLAB's applications.
Handle Graphics.
This is the MATLAB graphics system. It includes high-level commands for two-dimensional and three-dimensional data visualization, image processing, animation, and presentation graphics. It also includes low-level commands that allow you to fully customize the appearance of graphics as well as to build complete Graphical User Interfaces on your MATLAB applications.
The MATLAB mathematical function library.
This is a vast collection of computational algorithms ranging from elementary functions like sum, sine, cosine, and complex arithmetic, to more sophisticated functions like matrix inverse, matrix eigenvalues, Bessel functions, and fast Fourier transforms.
The MATLAB Application Program Interface (API).
This is a library that allows you to write C and Fortran programs that interact with MATLAB. It include facilities for calling routines from MATLAB (dynamic linking), calling MATLAB as a computational engine, and for reading and writing MAT-files.
Uses of Matlab
Matrix Laboratory or MATLAB for short is a multi-paradigm numerical computing environment and proprietary programming language developed by Mathworks. It combines computation, visualization, and programming in an easily usable environment and is all expressed in mathematical equations. Written in C, C++, and Java, Matlab was initially released in 1984. The latest version has been released on March 2018.
Applications of Matlab is built around the Matlab scripting language and revolves based on the following mathematical concepts:
Top Uses of Matlab
Matlab is a numerical computing environment. According to the Matlab website, the environment is designed for the following uses.
Embedded Systems
Embedded systems are computer systems consisting of hardware and software components and are designed to do a specific task. Some examples of embedded systems are washing machines, printers, automobiles, cameras, industrial machines, etc. With the push of one button, Matlab allows us to generate code and run it on hardware.
Control systems
Another most common reasons why the use of Matlab is important is that it provides control to device and system. A control system is responsible for managing, giving commands and regulating the behavior of other devices or systems. It is based on control loops. The devices or systems being controlled can range from simple home heaters to large industrial control systems that control the processes or the machines. The control system toolbox of Matlab provides algorithms and apps for systematically analyzing, designing and tuning linear control systems.
Digital signal processing
Digital signal processing is the usage of digital processing such as by computers or specialized digital signal processors to perform a range of signal processing operations. uses of Matlab products make it easy to use signal processing techniques to analyze time series data and also provides a unified workflow for the development of embedded systems and streaming applications.
