stats opsignal → tableimport fullseye as fs; fs.ledger.stat_describe(x) (実装を直接呼ぶなら import mathops; mathops.stat_describe(x)、台帳から引くなら opsmath.get("stat_describe"))Five-number-plus summary of a 1-D sample, as a plain dict.
Returns {"n", "mean", "std", "min", "max", "percentiles"} where
percentiles is {"p5", "p25", "p50", "p75", "p95"} (linear
interpolation between order statistics, numpy’s default). std is the
population standard deviation (ddof=0 — well-defined down to a
single sample; multiply by sqrt(n/(n-1)) for the sample estimator,
which is what :func:stat_covariance uses, documented there).
The tails matter in metrology: mean/std of residuals say how good
the fit is on average; p5/p95 say how bad the outliers are —
report both, a fit can pass on RMS and fail on extremes.
HALCON: tuple_mean / tuple_deviation / tuple_min /
tuple_max (the percentile row has no single HALCON tuple operator).
mathops の全 op は入力を検証してから計算する(黙って通さない):
ValueError — float64 への強制変換は虚部を黙って捨てる(numpy は ComplexWarning だけ出して「もっともらしく間違った」実数を返す)。.real/.imag/abs() を明示するか、複素対応の complexops を使う。ValueError — マスクを剥がして下の生値を使う暗黙変換を拒否。埋める/落とすを明示する。ValueError(件数を明示して拒否 — 結果全体に伝播するため)。ValueError。reshape を明示する)。stat_histogram の bins は mathops.MAX_ELEMENTS(2^26 ≈ 6700 万要素)超で ValueError。py -3.11 examples/math_metrology.pypy -3.11 examples/poc_thermal_radiometry.pytable を入力に取れる)—
