Developed primarily by Cleve Moler in the 1970s using FORTRAN subroutines. Rewritten in C in the 1980s with more functionality, which also include plotting features. The MathWorks Inc. was created (1984) to market and continue development 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.
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.
It is a high level language for technical computation. Matlab High Level Languages such as C, Pascal etc. Assembly
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

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.
