function op• 数据种类:signal → pairs
• 调用: import fullseye as fs; fs.ledger.invert_funct_1d(y)(要直接调用实现,import funct1d; funct1d.invert_funct_1d(y);从台账取用则 ops1d.get("invert_funct_1d"))
• 经台账调用的返回值: fullseye.ledger.invert_funct_1d(...) 只返回**声明的 out 类型 pairs 的值**(底层函数还会返回辅助信息)。需要被丢弃的部分时,使用 fullseye.ledger.invert_funct_1d.raw(...),或直接调用 funct1d.invert_funct_1d。
> 该算子的说明尚无译文,以下照原文给出。
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.
