Diagonal matrices diagonal matrices if a -(aj) is a square matrix, then the entries ai are called diagonal entries. a square matrix is called diagonal if all non-diagonal entries are zeros explore what happens if we add, subtract or multiply diagonal matrices. a and b are the same matrices in previous sections type d-diag(diag(a) ) to create a diagonal matrix from a. type e-diag(diag(b)) to create another diagonal matrix from b. find the following: » a) d+e ? b) d-e » c) de » d) ed answer the following questions . 1.) explain what type of matrix are you getting? » 2.) can you make an statement to generalize this fact? » 3.) is it possible to get a non diagonal matrix from adding or multiplying diagonal matrices? » 4.) can we obtain a diagonal matrix by multiplying two non-diagonal matrices? give an example » 5.) can we obtain a diagonal matrix by adding two non-diagonal matrices? give an example
