An exact equation for the matrix elements of the system of moments [the expectation values of the spherical harmonics], which govern the kinetics of the magnetization M of single domain particles is derived. This derivation is based on the representation of the stochastic Gilbert equation augmented...
Matrix Representation of Vectors The reader may have already noted that the operations of addition and multiplication by a scalar are defined in identical ways for vectors (Section 1.7) and the matrices we are calling column vectors. We can also use the matrix formalism to generate scalar products...
Using the results, we give some necessary and sufficient conditions for the system of matrix equations AX = C, XB = C over to have a reducible solution as well as the representation of such solution to the system when the consistency conditions are met. A numerical example is also given ...
If , a different way to obtain such low-rank representation may be to computing a separable approximation to f at the continuous level, namely , e.g., by the Emprical Interpolation Method (EIM) [4]. Then With at hand, Eq. (2.3) can be written as If a finite elements method is empl...
The set of equations may have no solution; that is, they may form an inconsistent system. 2. The set of equations, while consistent, may have an infinite number of solutions. 3. The set of equations may be both consistent and have exactly one solution. Solutions of simultaneous linear equa...
