## What is MAT LAB?

MATLAB is a high-performance mathematical computation, simulation, and programming environment software suite. It offers an immersive platform with hundreds of built-in advanced computing, graphics, and animation features. Matrix Laboratory is the abbreviation for MATLAB Software. MATLAB was created to apply the LINPACK (Linear system package) and EISPACK (Eigen system package) projects’ basic approach to matrix applications. MATLAB is a modern programming environment with advanced data structures, built-in editing and debugging facilities, and object-oriented programming support. In addition to the world, MATLAB is also a programming language. Although its name includes the term Matrix, MATLAB is all programming based on mathematical matrices and arrays. MATLAB’s all variable types contain data only in the context of an array, let it be an integer type, character type, or string type variable. MATLAB allows multiple task styles such as matrix manipulation, execution of an algorithm, data, and plotting functions and can interface with programmes in other programming languages.

The MATLAB was developed in the mid 1970s by the chairman of the Department of Computer Science at the University of New Mexico, Cleve Moler. Cleve expected his students to be able to use LINPACK & EISPACK (FORTRAN app libraries) without studying FORTRAN. In 1984, Cleve Moler tried to rewrite MATLAB in C with Jack Little & Steve Bangert and formed MathWorks. At the time, these libraries were known as JACKPAC, later revised as LAPACK for matrix manipulation in 2000. The integrated functions of MATLAB include excellent methods for linear algebra simulations, data analysis, signal processing, optimisation, numerical solution of ordinary differential equations, squares and a wide variety of other forms of mathematical calculations.

Any of these tasks use cutting-edge algorithms. There are various 2-D and 3-D graphics and animation capabilities.In order to run the programmes from MATLAB, MATLAB supports an external interface. The consumer is not restricted to built-in functions; he can use MATLAB to write his functions.

## History of MATLAB

Multiple optional “toolboxes” are also available from MATLAB developers. These toolboxes provide a set of functions for primary purposes such as symbolic calculations, image analysis, statistics, the architecture of the control system and neural networks.The matrix is the necessary construction components of MATLAB. The basic data form is the list. Vectors, scalars, actual matrices, and complex matrices are all processed automatically as key data form special cases. MATLAB likes matrices and functions of matrices. The integrated functions for vector functions are streamlined. Vectorized commands or codes thus run even more quickly in MATLAB.

## Main Features and Capabilities of MATLAB

• Environmental Development – This is the compilation of applications and installations to help you use MATLAB files and operations. Many of these tools are the user experience. It consists of a MATLAB desktop and command window, a command history, an editor and debugger, as well as browsers for support, working room, reports and search route.
• MATLAB Library of Mathematical Function- This is a comprehensive list of simple functions, such as number, sinus, cosine and complex mathematics, to more advanced features such as inverse matrix, self-values matrix, Bessel functions and Fourier’s quick transformation.
• Language MATLAB-This is a high-level array language with flow sentence, function, data structure, input/output and object-oriented programming. It allows “small programming” to quickly and dirty throw-out programmes and “broad programming” to construct massive and complicated application functions.
• Graphs Charts-MATLAB offers detailed vector and matrix displays as diagrams, and the possibility to annotate and print these graphs. It includes high-level frameworks for the simulation, animation, and display of two-dimensional and three-dimensional data. It also includes low-level frameworks, which allow us to completely customise graphics display and to create full graphical user interfaces on our MATLAB applications.
• MATLAB External  Interfaces/API- It is a library where we can write C and FORTRAN programmes interacting with MATLAB. It offers the capability to call MATLAB (dynamic link) routines, call MATLAB as a computer engine, and read and write MAT-files.

MATLAB Features

MATLAB can be used as a simulation device for different electrical networks but MATLAB has developed a highly competitive tool for artificial intelligence, robotics, imaging, wireless communications, machine learning, data analytics and more. While its use is vast, mainly used by circuit branches and mechanical engineering to solve a number of simple problems. It is a method for computing, scripting and visualising the results graphically.

As the name implies, MATLAB’s basic data element is the matrix or array. MATLAB toolboxes are properly constructed and allow you to make your creativity a reality. The programming of the MATLAB is quite similar to C and allows you to begin working with a little brush of your basic programming skills.

Advantage of MATLAB

Statistics and machine learning (ML)- This MATLAB toolbox can be very useful for programmers. It can effectively apply statistical techniques such as descriptive or inferential. The same is true in machine learning. Different models should be used to solve contemporary problems. The used algorithms can also be used for programmes of large data.

Fitting the curve- The toolbox for curve-fitting allows to interpret the pattern of data. After a certain trend is achieved, it can be a curve or a surface, the possible trends can be expected. Additional plotting, integral calculation, derivatives, interpolation etc may be performed.

System of control-Nature systems can be accessed. Control and observability of such factors as the closed-loop, the open-loop, the bode map, the Nyquist plot, etc. can be obtained. Different control methods like PD, PI and PID can be visualised. Time domain or frequency domain analysis may be performed.

Signal processing-In different engineering streams, signals and structures as well as digital signal processing are taught. Yet MATLAB offers the ability to visualise this properly. Different transformations like Laplace, Z etc. can be performed on any given signal. Validation of theorems could be possible. Analysis may be performed in the time or frequency domain. Multiple built-in functions are available.

The mapping processes-Mapping has many uses in different fields. For example, the MapReduce tool is really important in big data and has many implementations in the real world. Data mapping can be used for theft investigation or financial fraud detection, regression simulations, contingency analysis, social media prediction methods, data tracking, and so on.

Deep learning-It’s a form of machine learning that can be used for things like speech recognition, detecting financial fraud, and analysing medical images. Time-series analysis, artificial neural networks (ANN), fuzzy logic, or a mixture of these methods may all be used.
