Matrix vector products as linear transformations
Matrix multiplication or matrix products with vectors is always a linear transformation. And this is a bit of a side note. In the next video I'm going to show you that any linear transformation-- this is incredibly powerful-- can be represented by a matrix product or by-- any transformation on any vector can be equivalently, I guess, written as ...
