WebSep 16, 2024 · When a matrix is similar to a diagonal matrix, the matrix is said to be diagonalizable. We define a diagonal matrix D as a matrix containing a zero in every entry except those on the main diagonal. More precisely, if dij is the ijth entry of a diagonal matrix D, then dij = 0 unless i = j. Such matrices look like the following. WebTwo diagonalizable matrices and commute ( ) if they are simultaneously diagonalizable (that is, there exists an invertible matrix such that both and are diagonal ).
