Mat Lab Dot Product Of Two Vectors

Dot product in this activity you will utilize matlab to evaluate the dot product of two vectors in two different ways using the dot command and using matrix multiplication.

Mat lab dot product of two vectors.

U n v n. A vector is an ordered n tuple which may be represented as a matrix in the form of a column vector nxi matrix or a row vector 1x matrix. For example let s say that we have vectors u and v where u 1 0 and v 2 2. If the dot product is equal to zero then u and v are perpendicular.

The scalar output y is equal to the matlab operation y sum conj u1 u2 where u1 and u2 represent the input vectors. We can conclude that if the inner product of two vectors is zero the vectors are orthogonal. B a b cos theta we will use this formula later to find the angle theta. The scalar dot product of two real vectors of length n is equal to u v i 1 n u i v i u 1 v 1 u 2 v 2.

The dot product or scalar product of two vectors is used among other things as a way of finding the angle theta between two vectors. Dot product of two vectors a a1 a2 an and b b1 b2 bn is given by a b ai bi dot product of two vectors a and b is calculated using the dot function. Recall that given vectors a and b in space the dot product is defined as.
