Why is this down-voted? I was going to add most people have already seen some sort of linear algebra even in high school. Determinants, Gaussian elimination, etc.
It's unclear what "linear algebra" means to GP, though. I agree writing linear algebra libraries is next level, since that involves numerical code and knowing FP math well.
The number of American (and most other countries too) students who interacted with Gaussian elimination or Determinants in High School can fairly safely be rounded down to zero.
