2022年9月17日 · The transpose of a matrix is an operator that flips a matrix over its diagonal. Transposing a matrix essentially switches the row and column indices of the matrix.
Transpose - Wikipedia
In linear algebra, the transpose of a matrix is an operator which flips a matrix over its diagonal; that is, it switches the row and column indices of the matrix A by producing another matrix, often denoted by A T (among other notations).

2012年2月1日 · Definition The transpose of an m x n matrix A is the n x m matrix A T obtained by interchanging rows and columns of A , Definition A square matrix A is symmetric if A T = A .
Matrix transpose times itself - Mathematics Stack Exchange
We define A to be a matrix in Rm∗n R m ∗ n. Does ATA A T A have any particular structure? When is ATA A T A invertible? I know that the transpose of a matrix times itself is square and symmetric. Any help for the second? Some of the properties …
Transpose: if A is a matrix of size m n, then its transpose AT is a matrix of size n m. Identity matrix: I n is the n n identity matrix; its diagonal elements are equal to 1 and its o diagonal elements are equal to 0. Zero matrix: we denote by 0 the matrix of all zeroes (of relevant size).

Transpose of a Matrix. Another important operation on matrices is that of taking the transpose.For a matrix , we denote the transpose of by .Before formally defining the transpose, we explore this operation on the following matrix. \begin{equation*} \begin{bmatrix} 1 & 4 \\ 3 & 1 \\ 2 & 6 \end{bmatrix}^{T}= \begin{bmatrix} 1 & 3 & 2 \\ 4 & 1 & 6 \end{bmatrix} \end{equation*}
