Introduction of MATLAB For Engineers| Features & Applications

In this article, we will introduce MATLAB and discuss its significance.

What is MATLAB? | Definition & History

MATLAB, which stands for MATrix LABoratory, is a fourth-generation high-level programming language developed by MathWorks.

To fully appreciate MATLAB, it’s important to understand its history and the contributions of its inventor. After 1970, MATLAB was initially introduced by Cleve Moler, a co-founder of MathWorks.

For nearly 50 years, MATLAB has undergone extensive modifications and innovations, resulting in the release of more than 40 software versions.

Introduction of MATLAB Software for Engineers

Upon launching MATLAB, you will encounter two main components:

1. MATLAB Programming
2. MATLAB Simulink

Let us explore each of these components in detail:

1. MATLAB Programming

MATLAB uses high-level programming languages like C, C++, Fortran, and Java.

Last March 2019, the latest version of MATLAB R2019a was released. And this latest version, we can easily use Python language for writing the program.

When you start MATLAB software, you will see four main windows on your MATLAB desktop.

• Command Window:

The Command Window is the primary interface for entering and executing programming commands in MATLAB. It features a command prompt where users can input and execute commands.

• Command History:

The Command History window records all previously entered commands, providing a convenient way to review and reuse past commands.

• Current Folder:

The Current Folder window displays the MATLAB project folders and files that are currently saved. It helps users navigate and manage their files efficiently.

• Workspace:

The Workspace window shows all variables along with their types and sizes from the Command Window. It provides a comprehensive view of the data available in the current session.

MATLAB’s library is organized into multiple sections, each offering various functions. Familiarity with these basic sections and their functions is essential for effective programming and utilization of MATLAB.

2. MATLAB Simulink

MATLAB Simulink is an integrated environment for modeling, simulating, and analyzing dynamic systems. It helps to enhance MATLAB’s capabilities by providing a graphical user interface for building and simulating models of complex systems.
