This is MATLAB's 10 most easy & most basic programs that I's supposed to submit in my practicals. In this document I've complied 10 MATLAB programs from basic to advanced through intermediate levels, But overall they are for beginners only. It's only a 26 pages doc. for academic purposes. well, What else a student can offer you, huh? LOLz
3. WHAT IS MATLAB?
“AN INTRODUCTION”
• It stands for MATrix LAbORATORY
• It is developed by The Mathworks Inc.
• It is an interactive, integrated, environment
• For numerical computations
• For symbolic computations
• For scientific visualizations
• It is a high level programming language
• Program runs in interpreted, as opposed to compiled, mode
• MATLAB is a high level technical computing language and interactive environment for
algorithm development, data visualization, data analysis and numeric computation. Using
the MATLAB product, you can solve technical computing problems faster than the
traditional programming languages such as C, C++ and FORTRAN.
• You can use MATLAB in a wide range of applications, including signal and image processing,
communication, control design, test and measurement, financial modeling and analysis, and
computational biology. Add on toolboxes(collection of special purpose MATLAB functions,
available separately) extend the MATLAB environment to solve particular classes of
problems in these application areas.
• MATLAB provides a number of features for documenting and sharing your work. You can
integrate your MATLAB code with other languages and applications, and distribute your
MATLAB algorithms and applications.

4. Characterstics Of MATLAB:
• Programming Language Based(principally) On Matrices.
• Slow compared with FORTRAN or C because it is an interpreted language, i.e not pre‐
compiled. Avoid for loops, instead use vector form whenever possible.
• Automatic memory management, i.e you don’t have to declare arrays in advance.
• Intuitive, easy to use.
• Compact (array handling is Fortran 90‐like).
• Shorter program development time than traditional programming languages such as
FORTRAN and C.
• Can be converted into C code via MATLAB compiler for better efficiency.
• Many applications‐ specific toolboxes available.
• Coupled with Maple for symbolic computations.
• On shared‐memory parallel computers such as the SGI Origin2000, certain operations
processed in parallel autonomously when computation load warrants.
KEY FEATURES:-
• High level language for technical computing.
• Development environment for managing code, files, and data.
• Interactive tools for iterative exploration, design and problem solving.
• Mathematical functions for linear algebra, statistics, Fourier analysis, filtering, optimization,
and numerical integration
• 2‐D and 3‐D graphical functions for visualizing data.
• Tools for building custom graphical user interfaces.
• Functions for integrating MATLAB based algorithm with external application and languages,
such as C, C++, FORTRAN, Java, and Microsoft Excel.
