It kind of bothers me that the parent and other readers here are passing off knowing linear algebra as some kind of esoteric skill. Linear algebra is a year 2 course in a undergraduate eduation. There are polished libraries to make it fast.
Unless you mean enough knowledge to be writing linear algebra libraries, there is no need to consider this skill a high hurdle.
