My advice is to just start a side programming project where you have to learn the concept. I think it's a much, much faster way of learning, to have to implement the technique, than to go through textbooks and exercises. I don't think most people who aren't career mathematicians will truly understand linear algebra until they write a few Matrix and Vector libraries in support of some other thing they are deeply interested in building.
