function opsignal → pairsimport fullseye as fs; fs.ledger.invert_funct_1d(y) (実装を直接呼ぶなら import funct1d; funct1d.invert_funct_1d(y)、台帳から引くなら ops1d.get("invert_funct_1d"))fullseye.ledger.invert_funct_1d(...) は宣言 out 型 pairs の値だけを返す(本体は補助情報も返す)。捨てられた側が要るときは fullseye.ledger.invert_funct_1d.raw(...)、または funct1d.invert_funct_1d を直接呼ぶ。Swap the roles of x and y: x = f^-1(y) (HALCON invert_funct_1d).
Returns {"x": y-values sorted ascending, "y": their original indices},
i.e. the (y, x) pairs ordered so the new abscissa is monotonic — ready for
numpy.interp-style lookup.
Honest limitation: this is a true inverse only when y is monotonic. A non-monotonic function is multi-valued; the sort interleaves its branches instead of resolving them (ties keep index order — numpy stable-ish argsort). An empty input returns two empty arrays.
:param y: 1-D function (may be empty).
:returns: dict {"x": float64 array, "y": float64 array}.
:raises ValueError: non-1-D / NaN / Inf input.
