local_min_max_funct_1d — ONED function op

• 数据种类:signal → table

• 调用: import fullseye as fs; fs.ledger.local_min_max_funct_1d(y)(要直接调用实现,import funct1d; funct1d.local_min_max_funct_1d(y);从台账取用则 ops1d.get("local_min_max_funct_1d"))

用法

> 该算子的说明尚无译文,以下照原文给出。

Indices of strict local maxima / minima (HALCON `local_min_max_funct_1d`).

`{"max": indices, "min": indices} where index i` is a maximum iff

`y[i] > y[i-1] and y[i] > y[i+1]` (mirrored for minima). Inputs shorter

than 3 samples have no interior point and return two empty arrays

(degenerate case, not an error).

Honest limitation: inequalities are strict — plateau extrema (equal

neighbouring samples at the top/bottom) are not reported, and the boundary

samples `0 and n-1` are never extrema.

:param y: 1-D function (may be empty).

:returns: dict `{"max": int array, "min": int array}`.

:raises ValueError: non-1-D / NaN / Inf input.
