MATLAB is a high-performance language for technical
computing. It integrates computation, visualization, and programming
environment. Furthermore, MATLAB is a modern programming language
environment: it has sophisticated data structures, contains built-in
editing and debugging tools, and supports object-oriented programming.
These factors make MATLAB an excellent tool for teaching and research. MATLAB
has many advantages compared to conventional computer languages (e.g. C,
FORTRAN) for solving technical problems. MATLAB is an interactive system whose basic
data element is an array that does not require dimensioning. The
software package has been commercially available since 1984 and is now
considered as a standard tool at most universities and industries worldwide. It
has powerful built-in routines that enable a very wide variety of
computations. It also has easy to use graphics commands that make the
visualization of results immediately available. Specific applications are
collected in packages referred to as toolbox. There are toolboxes for
signal processing, symbolic computation, control theory, simulation, power
system engineering, optimization, and several other fields of applied science
and engineering.
MATLAB allows you to focus on your course work and
applications rather than on programming details. It enables you to solve many
numerical problems in a fraction of the time it would take you to write a
program in a lower level language. MATLAB helps you better understand and apply
concepts in applications ranging from engineering and mathematics to chemistry,
biology, and economics. MATLAB products are used in a broad range of
industries, including automotive, aerospace, electronics, environmental,
telecommunications, computer peripherals, finance, and medical. More than 500,000
technical professionals at the world’s most innovative technology companies, government
research labs, financial institutions, and at more than 2,500 universities rely
on MATLAB and Simulink as the fundamental tools for their engineering and
scientific work.
Simulink, a companion program to MATLAB, is an interactive
system for simulating nonlinear dynamic systems. It is a graphical mouse-driven
program that allows you to model a system by drawing a block diagram on the
screen and manipulating it dynamically. It can work with linear, nonlinear, continuous-time,
discrete-time, multirate, and hybrid systems. Blocksets are add-ons to
Simulink that provide additional libraries of blocks for specialized
applications like communications, signal processing, and power systems. Often it
is mistaken as a plug a play too be naive students but it this one is a
excellent modeling and design tool. Learning and designing in Simulink itself
is quite useful as well as resourceful in many ways.
This
course of MATLAB for Engineering Students is a document for an introductory course
in MATLAB and technical computing. This course does not provide a comprehensive
introduction or a complete coverage of MATLAB. Instead, it focuses on the
specific features of MATLAB that are useful for an engineer. The practice
sessions are used with one main goal: to allow students to become familiar with
computer software (e.g., MATLAB) to solve application problems. We assume that
the students have no prior experience with MATLAB. The availability of
technical computing environment such as MATLAB is now reshaping the role and
applications of computer laboratory projects to involve students in more
intense problem-solving experience. This availability also provides an opportunity
to easily conduct numerical experiments and to tackle realistic and more
complicated engineering problems.
Dear author, I want to know about you. could you please show yourself. I can't let it go without seeing who wrote such a good article.
