But, a "matrix" comes with the matrix multiplication we all know and love, right? The word doesn't just mean a 2d array. I think of it as a math term, not a CS data structure. More of a class, if you will, data and operations bound together. Not literally and not always, my analogy is imperfect, but, if you asked someone to perform an inner product on a block of numbers, you'd just confuse people if you said "matrix multiply".
