Workshop on MATLAB

Date/Time: Date(s) - 25/10/2022 - 26/10/2022( 8:00 am - 5:00 pm )
Location: Online


Overview

MATLAB is a high-level language that enables you to quickly perform computation and visualization through easy-to-use programming constructs. The training provides a gentle introduction to the MATLAB computing environment, and it is designed to provide participants a full understanding of MATLAB including popular toolboxes. The training consists of interactive lectures and sample MATLAB problems that generally they face. Hands-on sessions help participants with the syntaxes and functions for use in programming. The tool helps at various stages in studying subjects related to processing and analysis during regular subjects throughout courses. No prior programming experience or knowledge of MATLAB is assumed. Concepts covered include basic use, graphical representations, and tips for designing and implementing MATLAB code.

What is Matlab?

A programming language (like C, C++, Python) combined with a huge package of statistical and graphical tools. It is used by researchers across many fields to construct stimuli, run experiments, and analyze data. MATLAB is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problems and solutions are expressed in familiar mathematical notation. Typical uses include:

  • Math and computation
  • Algorithm development
  • Modeling, simulation, and prototyping
  • Data analysis, exploration, and visualization
  • Scientific and engineering graphics
  • Application development, including Graphical User Interface building

Objectives

  • to learn about the range of tools available in MATLAB
  • to learn how to start MATLAB and use the command window
  • to learn how to define and manipulate variables
  • to learn how to write simple scripts
