Example 0.16. Find the transpose of the following matrices: A = 1 2 3 4 5 6 ; B = 2 4 4 1 ; C = 2 4 1 2 0 3 5 Example 0.17. Verify that A = 2 5 3 7 and B = 7 5 3 2 are inverses of each other and then use this fact to solve the matrix equation Ax = b for b = 1 2 . Example 0.18. Use the emprical rule to nd the inverse of A = 2 5 3 7 Example 0.19 ...
Solution: First observe that if a matrix has dimensions n m then its transpose has dimensions m n. So if the matrix is equal to its transpose, we must have n = m|i.e.
