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.
