Params

ferreus_rbf.config.Params(kernel_type, solver_type=None, ddm_params=None, fmm_params=None, naive_solve_threshold=None, test_unique=None)

Configuration parameters controlling how an RBF system is solved.

A Params instance specifies solver options, accuracy targets, domain decomposition behaviour, fast multipole settings, and other controls for model fitting and evaluation.

Default values when Params isn't provided to RBFInterpolator:

• solver_type: Solvers.FGMRES
• ddm_params: Default DDMParams
• fmm_params: Default FmmParams
• naive_solve_threshold: 4096
• test_unique: true

Parameters:

Name	Type	Description	Default
kernel_type	RBFKernel	The RBFKernel variant being used.	required
solver_type	Optional[Solvers]	Iterative solver to use when fitting the RBF system.	None
ddm_params	Optional[DDMParams]	Parameters controlling domain decomposition preconditioning.	None
fmm_params	Optional[FmmParams]	Parameters controlling the fast multipole method (FMM).	None
naive_solve_threshold	Optional[int]	Threshold below which the system is solved directly rather than using iterative methods.	None
test_unique	Optional[bool]	Whether to test for and remove duplicate source points. This is highly recommended, as in order to ensure a unique solution to the RBF, the source points must be unique.	None
