  1. 1. Numerical Implementations of the Generalized Minimal Residual Method (GMRES)

    Kandidat-uppsats, Lunds universitet/Matematik LTH

    Författare :Ivo Dravins; [2015]
    Nyckelord :Generalized Minimal Residual Method; Jacobian-free; GMRES; Householder; Givens rotations; Gram-Schmidt; Mathematics and Statistics;

    Sammanfattning : The generalized minimal residual method (GMRES) is an iterative method used to find numerical solutions to non-symmetric linear systems of equations. The method relies on constructing an orthonormal basis of the Krylov space and is thus vulnerable to an imperfect basis caused by computational errors. LÄS MER

  2. 2. Linear Algebra for Array Signal Processing on a Massively Parallel Dataflow Architecture

    Kandidat-uppsats, Högskolan i Halmstad/Sektionen för Informationsvetenskap, Data– och Elektroteknik (IDE)

    Författare :Süleyman Savaş; [2009]
    Nyckelord :Am2000 family; Ambric register; aDesigner; radar; antenna arrays; beamforming; QRD; Gentleman-Kung systolic array; Givens Rotations; MPPA; massively parallel processor array; fixed point;

    Sammanfattning : This thesis provides the deliberations about the implementation of Gentleman-Kung systolic array for QR decomposition using Givens Rotations within the context of radar signal processing. The systolic array of Givens Rotations is implemented and analysed using a massively parallel processor array (MPPA), Ambric Am2045. LÄS MER
