Introduction toMATLAB
Developed primarily by Cleve Moler in the 1970's using FORTRAN subroutines.
Rewritten in C in the 1980's with more functionality, which also include plotting features.
The MathWorks Inc. was created (1984) to market and continue development of MATLAB.
History of MATLAB
The name MATLAB stands for MATrix LABoratory.
It is a package for scientific and technical computations and modeling.
It was originally designed for solving linear algebra type problems using matrices.
MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming environment.
MATLAB
The MATLAB environment is command oriented somewhat like UNIX. A prompt appears on the screen and a MATLAB statement can be entered. When the <ENTER> key is pressed, the statement is executed, and another prompt appears.
MATLAB now has built-in functions for solving problems requiring data analysis, signal processing, optimization, and several other types of scientific computations.
It also contains functions for 2-D and 3-D graphics and animation.
MATLAB (contd..)
It is a high level language for technical computation.
EVOLUTION OF MATLAB
Assembly
High Level Languages such as
C, Pascal etc.
Matlab
MATLAB is case sensitive. The fundamental data type is an array. Has ability to make functions in command
window in a single line. Can be linked to C/C++, JAVA, SQL, etc. Specific applications are collected in
packages referred to as toolbox. It is possible to keep track of everything
done during a MATLAB session.

Simulink software models, simulates, and analyzes dynamic systems.
Simulink supports linear and nonlinear systems, modeled in continuous time, sampled time, or a hybrid of the two.
Used to model and solve real problems in a variety of industries, including: • Aerospace and Defense• Automotive• Communications• Electronics and Signal Processing• Medical Instrumentation
Simulink
Example (closed-loop system)
Control System Toolbox Image Processing Toolbox Signal Processing Toolbox Financial toolbox Statistical Toolbox Communication Toolbox Neural Network Toolbox Fuzzy Logic Toolbox Aerospace Toolbox Fixed Income Toolbox
MATLAB Toolbox
MATLAB may behave as a calculator or as a
programming Language.
MATLAB combines calculation and graphic
plotting.
MATLAB is relatively easy to learn.
MATLAB is interpreted (not compiled), errors are
easy to fix.
MATLAB is optimized to be relatively fast when
performing matrix operations.
Strengths of MATLAB
Academics and scientific research. Defense applications Space exploration Artificial Intelligence Bio-informatics and medical science Forecasting Plant modelling Finance Security Systems Communication & Networking
Scope of MATLAB
Electronics Communication Chemical Biomedical Software industries Finance companies Instrument manufacturers Plant designing
Note:- It has extensive use in R&D department of almost all the big companies.
