Detailed Description

check types for requirements needed by interpolation

This helper struct provides compile-time information whether the provided Point and Value types can be used in the Acts::interpolate function.

Template Parameters

T	type of values to be interpolated
N	number of hyper box corners
P1	type for specifying the input point
P2	type for specifying the lower corner of the hyper box
P3	type for specifying the upper corner of the hyper box
