It pays to increase your word power

In mathematics, a matrix is said to be diagonally dominant if in every row of the matrix, the magnitude of the diagonal entry in that row is larger than or equal to the sum of the magnitudes of all the other (non-diagonal) entries in that row, and if in at least one row of the matrix, the magnitude of the diagonal entry in that row is strictly larger than the sum of the magnitudes of all the other (non-diagonal) entries in that row.
Not the same thing as dominatrix then (for words see Diagon Alley, for wine see Domina).
