EmoryMLIP / PNKH BMATLAB Implementation of our Projected Newton-Krylov Method for Bound-Constrained Optimization
aladshaw3 / Pjfnk MatlabThis repository is for an implementation of the Preconditioned Jacobian-Free Newton-Krylov method in Matlab
cheshirepezz / IPiC2DCollection of fully implicit PiC model in 2D on a Yee lattice, using Newton-Krylov non-linear solver
nla-group / PdeoptimSpectral-in-time Newton-Krylov solver for nonlinear PDE-constrained optimization
namdi / JFNK IntegratorThis contains code for a group of numerical integrators for time-dependent differential equations. They include the backward (implicit) Euler method, Spectral Deferred Corrections (SDC) method, and a Jacobian-Free Newton Krylov (JFNK) method designed to accelerate the convergence of SDC for stiff systems.
