rot_scale_to_matrix — REPRCONV `algebra` op

• Data kinds: rot_scale → matrix

• Call: import reprconv; reprconv.rot_scale_to_matrix(rot_scale) (or opsreprconv.get("rot_scale_to_matrix"))

Usage

`(angle [deg], scale) → a 2-D similarity matrix (2,2). The exit from rot_scale`.

> The detailed description below is the original text — the summary and the headings are translated.

`match_logpolar_z` が返す 2-tuple をそのまま行列にする。

:func:matrix_to_rot_scale と往復して実測 max|Δ| = 2.8e-14(角度は度、倍率は無次元)。

Args:

rot_scale: 長さ 2 の列 `(angle_deg, scale)`。scale > 0。

Returns:

(2, 2) float64。

Raises:

ValueError: 長さが 2 でない / scale <= 0 / 非有限。
