Dang it! I thought this was gonna be a cookbook from the movie Matrix. Like how to bake the cookies the oracle made, or the steak Cypher ate. That looked good.
I often say: "If Neo had simply read Linear Algebra textbooks instead of hacking around all night long, we would have known that the matrix is a representation of a linear map (morphism of vector spaces) with respect to given bases in the domain and codomain.".
Mathematics lets you see and understand the matrix.
