The MATLAB system

Posted by Shahrul

The MATLAB system consists of these main parts:

Desktop Tools and Development Environment.[6]

This part of MATLAB is the set of tools and facilities that help to use and become more productive with MATLAB functions and files. Many of these tools are graphical user interfaces. It includes:

  • The MATLAB desktop and Command Window,
  • An editor and debugger,
  • A code analyzer,
  • Browsers for viewing help,
  • The workspace,
  • Folders.

Mathematical Function Library.[6]

This library 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 Language.[6]

The MATLAB language 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 programs you do not intend to reuse. You can also do "programming in the large" to create complex application programs intended for reuse.

Graphics.[6]

MATLAB has extensive facilities for displaying vectors and matrices as graphs, as well as annotating and printing these graphs. It includes high-level functions for two-dimensional and three-dimensional data visualization, image processing, animation, and presentation graphics. It also includes low-level functions that allow you to fully customize the appearance of graphics as well as to build complete graphical user interfaces on your MATLAB applications.

External Interfaces.[6]

The external interfaces library allows you to write C and Fortran programs that interact with MATLAB. It includes facilities for calling routines from MATLAB (dynamic linking), for calling MATLAB as a computational engine, and for reading and writing MAT-files.

What is MATLAB?

Posted by Shahrul

The MATLAB high-performance language for technical computing integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation.[6] Typical uses include

  • Math and computation

  • Algorithm development

  • Data acquisition

  • Modeling, simulation, and prototyping

  • Data analysis, exploration, and visualization

  • Scientific and engineering graphics

  • Application development, including graphical user interface building

MATLAB is an interactive system whose basic data element is an array that does not require dimensioning. It 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. Today, MATLAB engines incorporate the LAPACK and BLAS libraries, embedding 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.

Electric machines play an important role in industry as well as our day to day life. They are used to generate electrical power in power plants and provide mechanical work in industries. They are also an indispensable part of our daily lives. Electric machines are very important pieces of equipment in our everyday lives. The DC machine is considered to be basic electric machines.

The aim of this final year project is to introduce students to the modeling of power components and to use computer simulation as a tool for conducting transient and control studies. Simulation can be very helpful in gaining insights to the dynamic behavior and interactions that are often not readily apparent from reading theory. Simulation is often chosen by engineers to study transient and control performance or to test conceptual designs.

MATLAB/SIMULINK is used because of the short learning curve that most students require to start using it, its wide distribution, and its general purpose of nature. This will demonstrate the advantages of using MATLAB for analyzing power system steady-state behavior and its capabilities for simulating transients in power systems and power electronics, including control system dynamic behavior
