warp.optim.linear

Iterative linear solvers for sparse linear systems.

This module provides GPU-accelerated iterative methods for solving linear systems, including conjugate gradient (CG), biconjugate gradient stabilized (BiCGSTAB), conjugate residual (CR), and generalized minimal residual (GMRES) methods.

API
