Introduction to MATLAB

MATLAB (Matrix Laboratory) is a high-level programming language and interactive environment designed by MathWorks for numerical computing and visualization. It's used extensively for matrix manipulations, plotting of functions and data, implementation of algorithms, and creation of user interfaces. MATLAB simplifies tasks like numerical integration, transformation, and solving differential equations, making it a tool of choice in engineering, scientific research, and quantitative finance. For example, MATLAB's built-in function 'fft' is used for computing the Fast Fourier Transform of a signal, enabling engineers to analyze frequency components quickly. Powered by ChatGPT-4o
