Public predicates

.. index:: fit/2 .. _interpolator_protocol/0::fit/2:

fit/2 ^^^^^^^^^

Fits an interpolant to a list of X-Y points using default options.

| Compilation flags: | static

| Template: | fit(Points,Model) | Mode and number of proofs: | fit(+list(pair),-compound) - one_or_error

| Exceptions: | Points is a variable: | instantiation_error | Points is not a valid list of at least two numeric points with distinct abscissas: | domain_error(interpolation_points,Points)

---

.. index:: fit/3 .. _interpolator_protocol/0::fit/3:

fit/3 ^^^^^^^^^

Fits an interpolant to a list of X-Y points using the given options.

| Compilation flags: | static

| Template: | fit(Points,Model,Options) | Mode and number of proofs: | fit(+list(pair),-compound,+list(compound)) - one_or_error

| Exceptions: | Points or Options is a variable: | instantiation_error | Points is not a valid list of at least two numeric points with distinct abscissas: | domain_error(interpolation_points,Points) | Options is a variable: | instantiation_error | Options is neither a variable nor a list: | type_error(list,Options) | An element Option of the list Options is a variable: | instantiation_error | An element Option of the list Options is neither a variable nor a compound term: | type_error(compound,Option) | An element Option of the list Options is a compound term but not a valid option: | domain_error(option,Option)

.. index:: evaluate/3 .. _interpolator_protocol/0::evaluate/3:

evaluate/3 ^^^^^^^^^^^^^^

Evaluates a fitted interpolant inside its data domain.

| Compilation flags: | static

| Template: | evaluate(Model,Argument,Value) | Mode and number of proofs: | evaluate(+compound,+number,-number) - one_or_error

| Exceptions: | Model is a variable: | instantiation_error | Model is not a model for the receiving interpolator: | domain_error(interpolation_model,Model) | Argument is a variable: | instantiation_error | Argument is not a number: | type_error(number,Argument) | Argument lies outside the fitted domain: | domain_error(interpolation_domain,Argument)
