Give an explicit expression for the inverse of the coefficient matrix, as a block 2-by-2 matrix. Hint: Use 2-by-2 block Gaussian elimination. Where have we previously seen the (2,1) block entry? Show how to use the QR decomposition of A to implement an iterative refinement algorithm to...
Question. The rank of a matrix is the dimension of the space spanned by its columns. Show that A has rank one if and only if A=ab^\textsf{T} for some (nonzero) column vectors a, b. Proof. Take A=(a_1, \dots, a_n) for its column vector representation. Then, r(A)=1 is...

Toward Solution of Matrix Equation X=Af(X)B+CScienceOpen
After assigning the boundary conditions to all boundary nodes using a collocation technique, Eq. (22) can be expressed in matrix form as(23)Hψ-Gψn=∑j=1N+Lαj(Hψˆj-Gψˆnj).Here, the Ci terms have been incorporated onto the diagonal element of H. If each of the vector ψ...

A circuit structure with systolic array is introduced in this paper in order to accelerate the speed of matrix inversion,which is quite prone to implement. 其中矩阵求逆是矩阵运算中重要的运算。 3. The algorithm unique capability of estimating fast time-varying and frequency-selective fading channel...
Solution of a matrix Wiener-Hopf equation connected with the plane wave diffraction by an impedance loaded parallel plate waveguide A matrix Wiener-Hopf equation connected with a new canonical diffraction problem is solved explicitly. We consider the diffraction of a plane electromagnet... A Büyükak...
On the other hand, the new class of diagrammatic Monte Carlo scheme15is claimed to have a “sign blessing” property which helps to reduce the effects of high-order diagrams. The state-of-the-art diagrammatic Monte Carlo scheme in the connected determinant mode (C-DET)16based on efficient ...
