Last Update: 2021/12/6


◆機能・用途(Purpose)

対角行列の転置行列を計算する。
Calculate the transpose of a diagonal matrix.
なお非正方行列の場合、対角行列であっても転置行列は元の行列と異なる。
Note that for a non-square matrix, the transpose of a diagonal matrix is different from the original one.

◆形式(Format)

#include <matrix/operation.h>
inline struct diagonal_matrix diagonal_matrix_transpose
(const struct diagonal_matrix A)


◆引数(Arguments)

A 元の対角行列\(\myvector{A}\)。
The original diagonal matrix \(\myvector{A}\).


◆戻り値(Return value)

\(\myvector{A}\)の転置行列を表す構造体。 戻り値のメンバの値は以下のようになる。
A structure which represents the transpose of \(\myvector{A}\). The values of members of the return value are as follows.
戻り値のメンバ
