WebA zero matrix is just a matrix with any dimensions that has all elements inside the matrix as 0. It does NOT have to be a square matrix. 2. You are right. Sal could have multiplied a 2x2 zero matrix with the 2x3 matrix to obtain a resulting zero matrix. Having a 2x3 zero matrix makes no difference as having a 3x3 matrix. Webcommutator so is Z because they have the same zero Trace.) Lemma 2: Suppose no matrix B –1 SB similar to a given square matrix S can have 0 as its ﬁrst diagonal element no matter how matrix B is chosen so long as it is invertible.

WebA zero matrix is indicated by O O, and a subscript can be added to indicate the dimensions of the matrix if necessary. The multiplicative property of zero states that the product of any n\times n n×n matrix and the n\times n n ×n zero matrix is the n\times n n ×n zero matrix. In other words, A\cdot O=O\cdot A=O A⋅O = O ⋅A = O.
