get_y_value_funct_1d — ONED function op

• データ種: signal → measurement
• 呼び出し: import fullseye as fs; fs.ledger.get_y_value_funct_1d(y, x, interpolate=True) (実装を直接呼ぶなら import funct1d; funct1d.get_y_value_funct_1d(y, x, interpolate=True)、台帳から引くなら ops1d.get("get_y_value_funct_1d"))

使い方

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.
