| Equality of Matrices |
|
| If two matrices have their corresponding elements equal, then they are called equal matrices. |
| |
If  then a = p, b = q, c = r and d = s. |
| |
 |
| |
 a = 7, b = 9, c = 3. |
| |
 |
| |
| (i) Two equal matrices are exactly the same. |
| |
| (ii) If rows are changed into columns and columns into rows, we get a transpose matrix. If the original matrix is A, its transpose is usually denoted by A' or At. |
| |
| (iii) If two matrices are of the same order (no condition on elements) they are said to be comparable. |
| |
For example, if  then its transpose matrix  |
| |
 |
| |
| If the given matrix A is of the order m x n, then its transpose will be of the order n x m. |
