The matrix
Unitary
Orthogonal
nil potent
involutory
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
A
AT
A2 = A
B2 = B
AB ≠ BA
AB = BA
If A is ( aij ) m × n and B = ( bjk ) m × p, then order of AB is
m × n
m × p
p × m
5 A
10 A
16 A
32 A
