pairs_to_signal — REPRCONV pairs op

• Data kinds: pairs → signal

• Call: import reprconv; reprconv.pairs_to_signal(pairs) (or opsreprconv.get("pairs_to_signal"))

Usage

Pairs `(N,2) → the dependent variable as a signal (N,). The second exit from pairs`.

列 1(y)だけを取り出す。`funct_1d_to_pairs` が (x, y) を並べた

(N,2) を返すので、その逆向きにあたる —— x が等間隔ならば

`signal -> pairs -> signal` は bit 一致する。等間隔でない x を持つ対を

通すと、x の情報が黙って落ちる(`signal` は添字が等間隔だという前提の型)。

だから :func:pairs_to_table が `x_uniform` を必ず一緒に出す。

Args:

pairs: (N, 2) または 2 本の等長 1-D のタプル。

Returns:

(N,) float64。

Raises:

ValueError: 形状不正 / 非有限。
