Leading eigenpairs
WebThe eigenvalues are not necessarily ordered. The resulting array will be of complex type, unless the imaginary part is zero in which case it will be cast to a real type. When a is … WebThe power method computes the leading eigenpair of a matrix. Coupled with a deflation process, the following eigenpairs can be computed. But this specific algorithm is not efficient in terms of performance. A more efficient method called subspace iteration method, based on an object called Rayleigh quotient is introduced in this project.

WebIdentifying the sources of crustal reflections is essential for deriving more geological information from deep crustal reflection profiles. Theoretical and model studies help place constraints on the role of compositional variation in producing deep crustal reflections. WebWe present a new algorithm that computes eigenvalues and eigenvectors of a Hermitian positive definite matrix while solving a linear system of equations with Conjugate Gradient (CG). Traditionally, all the CG iteration…
