I appreciate the help with solving my problem, though I do have some comments/questions to make with regard to usability for new users:
Why can't matrices be allowed in SR in a nontrivial way? Or, for some function H(s), why cant the behavior H(1) = H(s=1) be the default behavior? I guess my issue is that there doesn't seem to be a simple/consistent way to define a function that works, and I believe there should be. Mathematica manages this functionality somehow, what makes it difficult here? I am certainly a fan of using lambda functions, but iirc they are from python and are not inherently Sage/mathematical objects, right? Lambda functions aren't the "suggested" way to make functions in the Sage tutorial. Perhaps it is just not known to me, but I would love for there to be some *simple* consistent standard with defining functions such that, if I define one in this way and try to plot it or plug in values with a certain notation, it will Always work and not give me something weird like this. Does such a consistent notation exist that I haven't seen? The page "Some Common Issues with Functions" in the documentation essentially comments on the existence of this issue. Thanks for all of the help so far, I appreciate it!
