The elementary operations over vectors
A vector is a matrix that has only one row – then we call the matrix a row vector – or only one column – then we call it a column vector.
A row vector is of the form: .
A column vector is of the form: .
A quantity such as force, displacement, or velocity is called a vector and is represented by a directed line segment
A vector in the plane is directed line segment. The directed line segment has initial point A and terminal point B; its length is denoted by . Two vectors are equal if they have the same length and direction.
