The transpose of a matrix is found by creating new matrix where the rows and columns are swapped out. If i denotes row and j denotes column, we have a_(ij) becomes a_(ji).

Suppose you have a matrix A. The transpose is denoted A^T. Let us take a 2 x 2 matrix for simplicity.

a_(11) is row 1, column 1. The transposed entry would stay the in the same place.

a_(12) is row 1, column 2. The transposed entry would be placed in Row 2, Column 1a_(21).

a_(21) is row 2, column 1. The transposed entry would be placed in Row 1, Column 2a_(12).

a_(22) is row 2, column 2. The transposed entry would stay in the same place.
