• 呼叫: import fullseye as fs; fs.ledger.compose_funct_1d(y1, y2)(要直接呼叫實作,import funct1d; funct1d.compose_funct_1d(y1, y2);從台帳取用則 ops1d.get("compose_funct_1d"))
> 該運算子的說明尚無譯文,以下照原文給出。
Composition `y1(y2)`: the values of *y2* used as positions into *y1*
(HALCON `compose_funct_1d`).
Each `y2[i]` is rounded to the nearest integer and clamped into
`[0, len(y1) - 1], then out[i] = y1[that index]`. Nearest-neighbour
lookup, no interpolation.
Domain policy (documented difference from HALCON, which errors when the
range of *y2* leaves the domain of *y1*): out-of-domain positions are
clamped to the first / last sample of *y1*, never extrapolated. If you need
the strict check, compare `y_range_funct_1d(y2)` against
`x_range_funct_1d(y1)` before composing.
:param y1: outer function, at least 1 sample.
:param y2: inner function supplying positions (may be empty).
:returns: float64 array with the length of *y2*.
:raises ValueError: non-1-D / NaN / Inf input, or empty *y1*.
