Applications of MATLAB in Engineering

MATLAB has evolved from a numerical computing environment into a comprehensive engineering platform with rich toolboxes, modeling languages (Simulink, Stateflow), and code-generation capabilities. This paper surveys core applications of MATLAB across major engineering disciplines—electrical, electronics & communication, mechanical, civil, and computer engineering—emphasizing signal processing, control systems, power systems, image processing, communication systems, optimization, and machine learning. We present compact case studies, reproducible code snippets, and a discussion on performance, validation, and deployment (including embedded code generation). Limitations and best practices are articulated to guide students and practitioners in selecting MATLAB for research and industrial workflows.
