create_funct_1d_array — ONED function op

• Data kinds: signal → signal

• Call: import fullseye as fs; fs.ledger.create_funct_1d_array(y) (to call the implementation directly, import funct1d; funct1d.create_funct_1d_array(y); from the registry, ops1d.get("create_funct_1d_array"))

Usage

A 1-D function from equidistant samples (HALCON `create_funct_1d_array`).

Pure validation + float64 coercion: the returned array *is* the function,

on the implicit index grid. Accepts an empty sequence (an empty function).

:param y: 1-D sample sequence.

:raises ValueError: non-1-D / NaN / Inf input.
