* Switch to using new version of Lagrange polynomial interpolationjthorn2003-04-15
| | | | | | | | | | | which has separate tensor-product and maximum-degree interpolation operators, with the former now the default. This should fix the problem Yosef Zlowcher (sp?) found with the interpolant not being continuous in multiple dimensions. git-svn-id: http://svn.cactuscode.org/arrangements/CactusBase/LocalInterp/trunk@145 df1f8a13-aa1d-4dd4-9681-27ded5b42416

* Code changesjthorn2003-01-29
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | * support the same off-centering and boundary options as the new global interpolator (which needs the support here to work): this means changing the former parameter-table entry off_centering_tolerance to the new entries boundary_off_centering_tolerance boundary_extrapolation_tolerance * implement the N_boundary_points_to_omit parameter-table entry, (previously this was documented but not implemented) * completely rewrite the LocalInterp_molecule_posn() function and its test driver to support the above changes * change error return code from old CCTK_ERROR_INTERP_POINT_X_RANGE to new CCTK_ERROR_INTERP_POINT_OUTSIDE to avoid confusion with the old name suggesting that this was specific to the X coordinate * fix documentation of interpolation operator names for older (uniform Cartesian) CCTK_InterpLocal() interpolator -- this closes Erik Schnetter's bug report CactusBase/1367 Documentation changes * document the above code changes * much expanded description of molecule centering and boundary handling, including 2 new diagrams (done in latex picture mode :) * update README files to list all code files * move caching parameters (not implemented, and probably won't be implemented any time soon) out of documentation.tex into a new file future-ideas.tex * general cleanup of documentation.tex (not quite done, but 80% or so...) to more clearly describe what this thorn actually implements, rather than a generic spec of which this thorn only implements some pieces git-svn-id: http://svn.cactuscode.org/arrangements/CactusBase/LocalInterp/trunk@125 df1f8a13-aa1d-4dd4-9681-27ded5b42416
