Software Release 2015 (May 5, 2015)

We prepared a number of exciting new and updated [Software Releases] on a variety of topics and available from [GitHub]. To give you faster access to our recent work, we also included "beta" releases that, as the name suggests, are less polished hot-from-the-press software releases. Mathias Louboutin has kindly agreed to act as a contact person on behalf of Rafael Lago, who has left the group.

  1. Krylov solvers. (new in Master Branch) This package contains all the basic Krylov solvers (such as CRMN, CGMN and FGMRES) we use for computing an approximate solution for the wave equation. This is not a standalone package, but instead used extensively by our 3D Frequency-Domain Modeling Kernel. For questions contact Rafael Lago. [GitHub]
  2. Multigrid Preconditioners. (new in Master branch) A collection of multigrid preconditioners to be used together with FGMRES (from Krylov solvers package) for solving the time-harmonic wave equation. It implements some of the preconditioners from Calandra et al, but also extend and improve them for use with 27 points stencils. This is not a standalone package, but it is intended for use in the future by our 3D Frequency-Domain Modeling Kernel package. For questions contact Rafael Lago. [GitHub]
  3. 2D Frequency-domain acoustic modeling. (update in Master branch) This package contains a MATLAB implementation of a 2D frequency-domain constant-density acoustic modeling operator and its Jacobian as well as the analytic Greens function for constant and linearly increasing velocity. For questions contact Curt DaSilva. [GitHub]
  4. Wavefield Reconstruction Inversion. (update in Master branch) This toolbox provides functions that are the core for the Wavefield reconstruction Imaging application (SLIM-release-apps/applications/Imaging/WRimaging/) and the Wavefield Reconstruction Inversion application (not yet published). The scripts compute objective function values, gradients of the objective functions as well as a Gauss-Newton Hessian. For questions contact Curt DaSilva. [GitHub]
