Vector Multiplication Multiply vectors by multiplying each corresponding pair of component scalars from two operand vectors and accumulating the products. Result is a scalar, not a vector. Need to have a corresponding pair of component scalars implies vector lengths must be equal. Called a dot product or inner product (though the latter term refers as well to a more general linear algebra concept, not discussed until chapter 5).
