create_funct_1d_pairs — ONED function op

• データ種: signal × signal → signal
• 呼び出し: import fullseye as fs; fs.ledger.create_funct_1d_pairs(x, y) (実装を直接呼ぶなら import funct1d; funct1d.create_funct_1d_pairs(x, y)、台帳から引くなら ops1d.get("create_funct_1d_pairs"))

使い方

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.
