參考資料：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:
Math and computation
Algorithm development
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. 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.
About Simulink
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, multivariable, and multirate
system.
Blocksets are add-ins to Simulink that provide additional libraries of
block for specialized applications like communications, signal
processing, and power systems.
Real-time Workshop is a program that allows you to generate C code from
your block diagrams and to run it on a variety of real-time systems.

I compose.
I compose songs and poems in my mind.
But I don't have time to write them down,
so I decided to be a Mozar instead of a Mozart.
