MATLAB: A high-level programming language and environment primarily used for numerical computation, data analysis, visualization, and algorithm development. Uses scripting and functions (written in .m files). Ideal for mathematical modeling, data processing, control design, signal/image processing, and simulation through code. Example Applications: Signal processing algorithms Data visualization and plotting Solving differential equations Machine learning models Simulink: A graphical, block-diagram-based environment built on top of MATLAB for modeling, simulating, and analyzing dynamic systems. Allows you to design systems using drag-and-drop blocks rather than writing code. Best suited for multidomain simulations involving control systems, signal processing, and embedded systems. Example Applications: Control system design (e.g., PID control) Real-time simulations Model-based design for embedded systems (with auto code generation) Power electronics and mechanical systems modeling
