English Dictionary

orthogonal matrix

名詞

(linear algebra) A square matrix whose columns, considered as vectors, are orthonormal to each other. This implies that the transpose of such a matrix is also its inverse.

日本語の意味

直交行列：線形代数において、各列が互いに直交し（かつ正規化されている）正方行列を指す。すなわち、転置行列がその逆行列となる。

Because an orthogonal matrix preserves lengths and angles, it is often used to represent rotations and reflections in Euclidean space.

列ベクトルが互いに直交かつ単位長である正方行列は長さと角度を保ち、その転置が逆行列になるため、ユークリッド空間での回転や反射を表すのにしばしば使われる。
