Krylov v0.10.0

Diff since v0.9.10

Breaking changes

  • solve! is replaced by krylov_solve!
  • Update the API for workspaces (the suffix Solver is now Workspace)
  • Ensure that S is a concrete type in the workspaces
  • Update the API for workspace accessors (not exported anymore)
  • Rename some workspace accessors (iteration_count, solution_count, Aprod_count and Atprod_count)

New features

  • Add kdiv!, kscalcopy! and kdivcopy! for the support of custom workspaces
  • Add a generic interface (krylov_workspace, krylov_solve and krylov_solve!)
  • Add documentation on the generic API and the workspace accessors
  • Update the docstrings to add more cross-references
  • Add a function Krylov.elapsed_time

Other changes

  • Krylov.jl now requires Julia 1.10
  • Update the reference of MinAres and CAr
  • Return a nice error if we detect that the preconditioner is not SPD in CG
