What is the dot product of parallel vectors.

Using this result, the dot product of two matrices-- or sorry, the dot product of two vectors is equal to the transpose of the first vector as a kind of a matrix. So you can view this as Ax transpose. This is a m by 1, this is m by 1. Now this is now a 1 by m matrix, and now we can multiply 1 by m matrix times y.The specific case of the inner product in Euclidean space, the dot product gives the product of the magnitude of two vectors and the cosine of the angle between them.
