The result is a real scalar. The inner product of a vector with itself is related to the Euclidean length of the vector,norm(A). Dot Product of Matrices Create two matrices. A = [1 2 3;4 5 6;7 8 9]; B = [9 8 7;6 5 4;3 2 1]; ...
For complex vectors, the dot product involves a complex conjugate. This ensures that the inner product of any vector with itself is real and positive definite. u · v=n∑i=1‾uivi . Unlike the relation for real vectors, the complex relation is not commutative, sodot(u,v)equalsco...

If the dot product is equal to zero, then u and v are perpendicular. For complex vectors, the dot product involves a complex conjugate. This ensures that the inner product of any vector with itself is real and positive definite. u · v=n∑i=1‾uivi . Unlike the relation for...
In general, the dot product of two complex vectors is also complex. An exception is when you take the dot product of a complex vector with itself. Find the inner product of A with itself. Get D = dot(A,A) D = 8 The result is a real scalar. The inner product of a vector ...

it is, therefore, necessary to use the transpose operator to compute the dot (inner) product of W with itself: In [9]: print dot(W.T,W) ---> print(dot(W.T,W)) [[5]] In [10]: print np.asscalar(dot(W.T,W)) ---> print(np.asscalar(dot(W.T,W))) 5 ...

So if you want the dot product of each column vector of A with itself, you could useColDot = np.dot(np.transpose(A), A).diagonal(). On the other hand, if you want the dot product of each row with itself, you could useRowDot = np.dot(A, np.transpose(A)).diagonal(). ...
