WebbMatrix addition or subtraction is calculated by addition or subtraction of corresponding elements. As a result you get a new matrix with the same dimension. Up. WebbIndeed, such a matrix can be reduced, by appropriately adding multiples of the columns with fewer nonzero entries to those with more entries, to a diagonal matrix (without changing the determinant). For such a matrix, using the linearity in each column reduces to the identity matrix, in which case the stated formula holds by the very first characterizing … WebbThe associative laws state that when you add or multiply any three matrices, the grouping (or association) of the matrices does not affect the result.
