A matrix of order m×1 is called: |
- A. row matrix
- B. column matrix
- C. identity matrix
- D. scalar matrix
|
| 2 |
|
- A. scalarmatrix
- B. diagonalmatrix
- C. lower triangularmatrix
- D. uppertriangularmatrix
|
| 3 |
|
- A. scalar matrix
- B. diagonalmatrix
- C. triangularmatrix
- D. none of these
|

If A and B are two matrices, then: |
- A. A B = O
- B. AB = BA
- C. AB = I
- D. AB may not be defined
|

For a square matrix A, |A| equals: |
- A. A<sup>t</sup>
- B. |A<sup>t</sup>|
- C. -|A<sup>t</sup>|
- D. -A<sup>t</sup>
|
| 6 |
If two rows (or two columns) in a square matrix are identical (i.e. corresponding elements are equal), the value of the determinant is: |
|
| 7 |
If each element in any row or each element in any column of a square matrix is zero, then value of the determinant is: |
- A. 0
- B. 1
- C. -1
- D. none of these
|

If A is a square matrix, then: |
- A. |A<sup>t</sup>| = A
- B. |A<sup>t</sup>| = -A
- C. |A<sup>t</sup>| = |A|
- D. A<sup>t</sup>= A
