If I have two vectors of equal dimensions like 3×1 lets say, how am I able to multiply it with another vector of 3×1 dimension? Its not possible in matrix operation.
Edit: Seems like most of you didn't get my question. If vectors ARE matrices and A and B has the same dimensions (3×1), it should not have been possible to multiply no?

The dot product of two vectors is defined as
$$\bar{v} . \bar{u} = v^Tu$$
This would result in a $1 \times 1$ real number
