Introduction MATLAB (short for MATrix LABoratory) is a programming and numerical computing environment developed by MathWorks. Originally designed to facilitate matrix manipulation, it is now widely used in the fields of engineering, science, research, and finance. In addition to numerical computation, MATLAB also allows the modeling and simulation of dynamic systems using Simulink, a graphical extension that facilitates the design of complex block-based systems. Finally, thanks to its integration with other languages (C, Python, Java) and hardware platforms (Arduino, Raspberry Pi, etc.), MATLAB remains an essential tool for engineers and scientists looking to move quickly from prototype to concrete implementation. To download Matlab for free, the first step is to go to the following website [link].Here is the page that appears; click on “Get Matlab”: Next, click on Create an account: Next, enter your email address. If you do not have a professional or student license, you will be entitled to access the software with a trial period. You simply need to choose a password to complete the account creation: Once your email address is verified, your account is complete: If you are using a personal email address without a license, click on Continue anyway: You will then be taken to the Matlab homepage. Here you will have the option to install Matlab by clicking on “30-day trial version” and logging into your account from within the software.
