The Matrix `[[1,0,0],[0,2,0],[0,0,0]]` is a
a) diagonal matrix
b) symmetric matrix
c) skew symmetric matrix
d) scalar matrix

The matrix [(0,-5,8),(5,0,12),(-8,-12,0)] is a a) diagonal matrix b) symmetric matrix c) skew symmetric matrix d) scalar matrix

The matrix A=[0-5 8 5 0 12-8-12 0] is a (a) diagonal matrix (b) symmetric matrix (c) skew-symmetric matrix (d) scalar matrix

The matrix A=[{:(1,0,0),(0,2,0),(0,0,3):}] is: a) scalar matrix b) symmetric matrix c) skew symmetric matrix d) none f these

The matrix A=[(0,-5, 8),( 5, 0, 12),(-8,-12, 0)] is a (a) diagonal matrix (b) symmetric matrix (c) skew-symmetric matrix (d) scalar matrix

The matrix A=[(1, 0, 0),( 0, 2, 0),( 0, 0, 4)] is (a) identity matrix (b) symmetric matrix (c) skew-symmetric matrix (d) diagonal matrix

The matrix [{:(1,0,0),(0,2,0),(0,0,4):}] is a

......... Matrix is both symmetric and skew-symmetric matrix.

If A is symmetric as well as skew-symmetric matrix, then A is

If A is symmetric as well as skew-symmetric matrix, then A is

A matrix which is both symmetric as well as skew-symmetric is a null matrix.
