Matrix Algebra and Applications - UTEP
176 Chapter 3 Matrix Algebra and Applications quick Examples Matrix Addition and Subtraction Two matrices can be added (or subtracted) if and only if they have the same dimensions. To add (or subtract) two matrices of the same dimensions, we add (or subtract) the cor-responding entries. More formally, if A and B are m ×n matrices, then A + B and
