Detailed Description
Implementation of bilinear interpolation.
Member Function Documentation
◆ _interpolateXQ2() [1/2]
|
virtual |
Interpolate a single-point in (x,Q2), given x/Q2 values and subgrid indices.
The key function to be overridden in derived classes: the subgrid and x/Q2 index lookup (and their caching) are done centrally in the Interpolator base class so do not need to be re-implemented in each flavour of interpolator.
Implements LHAPDF::Interpolator.
◆ _interpolateXQ2() [2/2]
|
virtual |
Interpolate a single-point in (x,Q2), given x/Q2 values and subgrid indices, for all 11 standard flavours at once.
This can be overridden in derived classes for a more CPU-efficient implementation than the default looping over all flavours: often the grid coefficients for the point can be efficiently reused for each flavour.
Reimplemented from LHAPDF::Interpolator.
The documentation for this class was generated from the following file:
