aij = i-j/i+j ,when i=1 and j=1 , 1-1/1+1 = 0
when i=1 and j=2 , 1-2/1+2 = -1/3
when i=2 and j=1 , 2-1/2+1 = 1/3
when i=2 and j=2 , 2-2/2+2 = 0
[aij]^3 *4 , when aij = 0 , [0]^3*4 = 0
when aij = -1/3 , [-1/3]^3*4 = -4/27
when aij = 1/3 , [1/3]^3*4 = 4/27
when aij = 0 , [0]^3*4 = 0
therefore the matrix is |0 -4/27|
4/27 0|
