Vector Multiplication
Actually we don't use the term 'Multiplication' to vector (matrix) operation, because it may confuse you with numeric multiplication like '2 x 3' (two times three) or '4 x 6' etc. There is no such a simple multiplication in vector and matrix like this. In vector and matrix, we have a little bit complicated method and these method is usually called in Vector Product (Matrix Product). In addition, there are two different type of product. One is called 'Inner Product' and the other is called 'Outer product (cross product)'. Refer to Inner Product and Outer Product page for the details.
