Operasi Matriks (Pengurangan)
Pengurangan Matriks
Jika Amxn = (aij) dan Bmxn = (bij) ,maka A mxn – Bmxn = Cmxn =(cij), (aij) = (bij),
Contoh:
A = B = , maka A + B =
2 1 -2 4 , maka A + B = 2 1 – -2 4 = 4 5 = C = (cij)
3 2 3 2 3 2 3 1 0 1
A = B =
3 2 1 2 7 -2 ,
-2 3 4 3 -5 1
maka A + B =
3 2 1 – 2 7 -2 = 1 -5 3 = C (cij)
-2 3 4 3 -5 1 -5 8 3
