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 no
interactive 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.
Desktop Overview
Use desktop tools to manage your work in MATLAB. You can also use
MATLAB functions to perform the equivalent of most of the features found
in the desktop tools.
The following illustration shows the default configuration of the MATLAB
desktop. You can modify the setup to meet your needs.

The MATLAB System
The MATLAB system consists of five main parts:
Desktop Tools and Dvelopment Environment. This is the set of tools and
facilities that help you use MATLAB functions and files. Many of these
tools are graphical user interfaces. It includes the MATLAB desktop and
Command Window, a command history, an editor and debugger, and
browsers for viewing help, the workspace, files, and the search path.
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 Eigen values, Bessel functions, and fast Fourier transforms.
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 large and complex application programs.
Graphics. 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.
The MATLAB External Interfaces/API. This is a library that allows you to
write C and Fortran programs that interact with MATLAB. It includes
facilities for calling routines from MATLAB (dynamic linking), calling
MATLAB as a computational engine, and for reading and writing MAT-
files.
Programming:
Flow Control:
MATLAB has several flow control constructs:
if, else, and elseif
switch and case
for while
continue
break
try - catch
return
Several special functions provide values of useful constants:
