I've been answering questions on MATLAB, mathematics, physics, programming, and control systems since 2021, with over 200 solutions provided on Brainly, the MATLAB Help Center, and Stack Overflow. My areas of expertise include MATLAB programming and debugging, control systems (PID, LQR, state-space modeling), Simulink modeling and simulations, mathematics and physics (calculus, linear algebra, differential equations), and deep learning and AI with MATLAB. In addition to my strong background in these areas, I am also proficient in multiple programming languages including Python, C++, C, Java, JavaScript, MATLAB, and HTML. I speak English and use the pronouns he/him. If I've answered your question, follow me so you can message me anytime with future questions.
