The discussion centers on the choice between taking a course in MATLAB or discrete mathematics, with a consensus leaning towards discrete math. Participants argue that while MATLAB can be self-taught, discrete math is valuable for enhancing mathematical skills and may have relevance in physics. One user mentions a requirement for MATLAB at Georgia Tech, but expresses a desire to switch to physics, emphasizing the importance of discrete math. Self-study resources for discrete math are shared, including a recommended book and online lectures, highlighting the subject's appeal and utility. The urgency of making a decision before the schedule locks in is also noted.
