typed op• 資料種類:matrix → matrix
• 呼叫:fullseye.apply(img, "tb_stat_correlation", a=0.5, b=0.5)(2-D 的模型是一張圖 + 兩個純量旋鈕 a,b∈[0,1])

*圖為在 128×128 合成輸入上實際執行的輸出。左為輸入,右為輸出。點雲以俯視散點顯示(亮度 = z),一維序列為折線,體資料為沿 z 的最大值投影,影片為中間影格,複數影像為振幅;無法成像的回傳值直接顯示數值。*
*旋鈕 a 不改變輸出(實測: 0.1 / 0.5 / 0.9 相同)。*
*旋鈕 b 不改變輸出(實測: 0.1 / 0.5 / 0.9 相同)。*

> 以下的詳細說明為原文 —— 摘要與標題已翻譯。
Same orientation as :func:stat_covariance (rows = observations).
Entries are clipped to `[-1, 1]` (floating-point can overshoot by an
ulp), the diagonal is exactly `1` and the matrix exactly symmetric by
construction.
**A constant column raises `ValueError`** (naming the column) instead of
yielding NaN: correlation with a zero-variance variable is mathematically
undefined (0/0), and a NaN that surfaces three ops downstream is the
classic zero-division bug family this module fails closed against. Drop or
perturb the constant column deliberately if that is what you mean.
HALCON: no public tuple operator (see :func:stat_covariance).
Typed bridge of the math op `stat_correlation into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.

下面的範例呼叫的是底層帳本運算子 stat_correlation。此橋接運算子只是把同一實作適配為 fn(v, a, b) 慣例,行為完全相同(只是呼叫形式不同)。
