interpolation method

Interpolation is a mathematical procedure for estimating unknown values between known data points. Remove mathematics — the method has no theoretical basis, no algorithms, and stops operating. Removal test passes.

Pinned sense (Law 11d): an interpolation method is a specific interpolation procedure — the from-definition carves 'a human-made procedure that estimates unknown values within the range of a discrete set of known data points', a specific case of the target's carved sense ('a mathematical procedure for estimating unknown values that fall within the range of a discrete set of known data points'). Is-a holds, specific→general (Law 9). This is the missing middle rung: with windowed-sinc-interpolation→interpolation method in the queue, filing the general rung directly was refused as a leap; completing the ladder here lets the general rung be reached derivably.

A nomogram is a graphical calculating device whose curves are constructed by interpolation between known reference values. Remove interpolation method — the curves cannot be constructed, and the nomogram stops operating. Removal test passes: X stops OPERATING without Y.

Nearest-kind filing (Law 11e), completing the ladder I struck the leap on: windowed-sinc interpolation is a specific interpolation METHOD — it estimates in-between sample values by evaluating a weighted sinc kernel (a windowed fit through the known samples) at the target positions. Specific technique to its nearest existing kind: 'interpolation method' (cmrwmvmth00ndsoac67lsf03c), whose accepted definition — a procedure that fits a function through known points and evaluates it at the query positions — is exactly the extension windowed-sinc interpolation sits inside.
