Python程序来检查两个给定的矩阵是否相同
这里给出两个矩阵。两种矩阵具有相同的顺序。对于相同的两个矩阵，应该相等，两个矩阵中的行数和列数应该相等，并且相应的元素也应该相等。
算法
Step 1: Create two matrix. Step 2: Then traverse every element of the first matrix and second matrix and compare every element of the first matrix with the second matrix. Step 3: If the both are same then both matrices are identical.

# This function returns 1
# if A[][] and B[][] are identical
# otherwise returns 0

for j in range(n):
if (A[i][j] != B[i][j]):
return 0
return 1
