I'm currently writing my first conference paper and am trying to determine a variable naming convention. I like the approach used by Di Carlo in Dynamic Locomotion in the MIT Cheetah 3 Through Convex Model-Predictive Control:
[skipped irrelevant convention] Vectors are bold, upright, and lowercase (a,ω), matrices are bold, upright, and uppercase (A,Ω),and scalars are lowercase and italicized (a,ω).
The conference recommends following the IEEE guidelines outlined here, which does not comment on the topic. I assume it is thus up to me as the author to decide. Is bolding variables frowned upon? Is there a alternative, preferred method? Thank you!
