| Parameters: |
- data (
numpy.ndarray) – Numpy array of data to use for interpolation. Must have exactly two columns (x
and y data)
- child (
pybamm.Symbol) – Node to use when evaluating the interpolant
- name (str, optional) – Name of the interpolant. Default is None, in which case the name “interpolating
function” is given.
- interpolator (str, optional) – Which interpolator to use (“pchip” or “cubic spline”). Note that whichever
interpolator is used must be differentiable (for
Interpolator._diff).
Default is “cubic spline”. Note that “pchip” may give slow results.
- extrapolate (bool, optional) – Whether to extrapolate for points that are outside of the parametrisation
range, or return NaN (following default behaviour from scipy). Default is True.
- **Extends** (
pybamm.Function) –
