Equality of Matrices

definition

Two matrices A = [a_(ij)] and B = [b_(ij)] are said to be equal if
(i) they are of the same order
(ii) each element of A is equal to the corresponding element of B, that is a_(ij) = b_(ij) for all i and j.

For example, [(2,3),(0,1)] and [(2,3),(0,1)]  are equal matrices but

[(3,2),(0,1)]  and [(2,3),(0,1)] are not equal matrices. Symbolically,

if two matrices A and B are equal, we write A = B.
