in′ner prod′uct n. the quantity obtained by multiplying the corresponding coordinates of each of two vectors and adding the products, equal to the product of the magnitudes of the vectors and the cosine of the angle between them. Also calleddot product,scalar product. ...
MATRICES (Mathematics)We investigate the solutions of the Sylvester-type matrix polynomial equation A(λ)X(λ) Y (λ)B(λ) = C(λ), where A(λ), B(λ), and C(λ) are the polynomial matrices with elements in a ring of polynomials F[λ], F is a field, X(...
The magnitude of a vector x ∈ ℝn is the square root of the inner product of x with itself. ∎ If u and v are vectors in ℝn, then |(u,v)| ≤ ‖u‖ ‖v‖. ∎ An induced inner product on two matrices of the same order is obtained by multiplying corresponding elements ...
However, not every two matrices can be multiplied. If we consider A as m x n and B as k x l matrices, then for the resulting matrix C = A·B, n has to be equal to k, and, for matrix D = B·A, l must be the same as m. In other words, the number of columns of the ...
block matrix A = ( B 0 0 0 ) ∈ M n + r ( R ) A=\begin{pmatrix} B & 0 0 & 0 \end{pmatrix} \in M_{n+r}(R) , B ∈ M n ( R ) B\in M_n(R) , r ≥ 1 r\ge 1 , over a von Neumann regular separative ring R R , is a product of idempotent matrices. Fu...
