get_y_value_funct_1d — ONED function op

• 資料種類:signal → measurement

• 呼叫: import fullseye as fs; fs.ledger.get_y_value_funct_1d(y, x, interpolate=True)(要直接呼叫實作,import funct1d; funct1d.get_y_value_funct_1d(y, x, interpolate=True);從台帳取用則 ops1d.get("get_y_value_funct_1d"))

用法

> 該運算子的說明尚無譯文,以下照原文給出。

The y-value at (fractional) position *x* (HALCON `get_y_value_funct_1d`).

With `interpolate=True` (default) the value is linearly interpolated

between the two neighbouring samples; with `interpolate=False` the nearest

sample is returned.

Domain policy (documented, not extrapolated): *x* outside `[0, n-1]`

clamps to the boundary value (`numpy.interp` end-hold semantics /

index clip). HALCON's `'zero'`-border variant is not offered.

:param y: 1-D function, at least 1 sample.

:param x: finite scalar position in index units.

:param interpolate: linear interpolation (True) or nearest sample (False).

:returns: float.

:raises ValueError: non-1-D / NaN / Inf input, empty input, or non-finite *x*.
