interp_poly opsignal × signal × signal → signalimport fullseye as fs; fs.ledger.interp_linear(x, y, xq, out_of_range='raise') (実装を直接呼ぶなら import mathops; mathops.interp_linear(x, y, xq, out_of_range='raise')、台帳から引くなら opsmath.get("interp_linear"))Piecewise-linear interpolation of (x, y) samples at query xq.
x must be strictly increasing (fail-closed: an unsorted or duplicated grid raises rather than being silently reordered). xq is a scalar or a 1-D array; a scalar query returns a Python float, an array returns float64.
Out-of-range is an explicit choice, never silent: 'raise' (default)
refuses any query outside [x[0], x[-1]] — a calibration table queried
beyond its calibrated range is a wrong answer waiting to happen — while
'clamp' holds the boundary values (the honest flat extension; there is
deliberately no silent linear extrapolation mode).
Exact on the nodes and exact for data that is genuinely piecewise linear.
HALCON: get_y_value_funct_1d interpolates function pairs the same way
(see :mod:funct1d, which works HALCON’s index-grid convention; this op
takes an arbitrary strictly-increasing x grid).
