Suppose $a,b,c$ are matrices, and I want to define the set $S={a,b,c}$. What is the proper syntax for this? More generally, how do I define a set by specifying its elements (regardless of their nature). I am only finding documentation for sets of numbers.

I'm also interested in doing functions that take sets like $S$ as input. For instance, if I had a matrix $d$, I want to be able to define a set like $S'={da,db,dc}$, but I want to be able to do this via the Sage equivalent of $f(S):={ms\mid s\in S}$.
