function op• Data kinds: signal × signal → signal
• Call: import fullseye as fs; fs.ledger.create_funct_1d_pairs(x, y) (to call the implementation directly, import funct1d; funct1d.create_funct_1d_pairs(x, y); from the registry, ops1d.get("create_funct_1d_pairs"))
A 1-D function from arbitrary `(x, y) pairs, resampled to an equidistant grid (HALCON create_funct_1d_pairs`).
The pairs are sorted by x and linearly interpolated onto the integer
grid `floor(min(x)) .. ceil(max(x))` (step 1). Grid points outside the
convex hull of the data (only the two end points can be) hold the nearest
sample's value — `numpy.interp` end-hold, no extrapolation. Duplicate x
values keep numpy's interp behaviour (the segment between duplicates is a
step). Note the returned function's index 0 corresponds to physical
`x = floor(min(x))`, not necessarily 0.
:param x: 1-D abscissa values, at least 1 pair, finite.
:param y: 1-D ordinate values, same length as *x*, finite.
:returns: float64 array on the integer grid.
:raises ValueError: non-1-D / NaN / Inf input, empty input, or length mismatch.
