group MatrixTrans

Tranposes a matrix.

Transposing an M x N matrix flips it around the center diagonal and results in an N x M matrix.

\[\begin{split} \begin{pmatrix} a_{1,1} & a_{1,2} & a_{1,3} \\ a_{2,1} & a_{2,2} & a_{2,3} \\ a_{3,1} & a_{3,2} & a_{3,3} \\ \end{pmatrix}^T = \begin{pmatrix} a_{1,1} & a_{2,1} & a_{3,1} \\ a_{1,2} & a_{2,2} & a_{3,2} \\ a_{1,3} & a_{2,3} & a_{3,3} \\ \end{pmatrix} \end{split}\]

Transpose of a 3 x 3 matrix

Transposing an M x N matrix flips it around the center diagonal and results in an N x M matrix.
