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 Aᵀ. The transpose of a matrix was introduced in 1858 by the British mathematician Arthur Cayley.
