A square matrix A is singular if _______
| A | ≠ 0
| A | = 0
| A | = 1
| A | ≠1
A matrix is _______.
A collection of real numbers
A collection of real or complex numbers
An array of real numbers
An array of real or complex numbers
If A and B are matrices such that A + B and AB are defined, then.
It is not necessary that A and B are of the same size.
A and B are square matrices of the same order
No. of columns in A = no. of rows in B
None of these
Then 3 A - 4 B =
If matrics AB = 0.
A = 0 or B = 0
A = 0 and B = 0
It is not necessary that A = 0 or B = 0
Above statements are wrong.
If A is 3 x 4 matrix and B is a matrix such that A'B and B A' are both defined.Then B is of the type.
4 x 3
3 x 4
3 x 3
4 x 4
If A is a squre matrix, then A - A' is _____________.
Unit matrix
Null matrix
A
Skew symmetric matrix
If matrix contain 13 elements. Write the possible order of the matrix
2 × 3
13 × 2
1 × 13
6× 2
