The zero matrix is denoted by O or O mxn where O is a matrix of size mxn. This is simply a matrix with all zeros. Example: O = 0 0 0 0 ; or O = 2 4 0 0 0 0 0 0 3 5 Properties of the Zero Matrix 1. A+ O = A where it is understood that O has the same size as A. 2. A+ ( A) = O 3. If cA = O, then c = 0 or A = O. Matrix Multiplication: Matrix ...
Introduction to Matrix Operations in Matlab
