Penjelasan program matriks Nilai dimasukkan dan disimpan dalam variabel a1, a2, a3, a4, b1, b2, b3, b4 dan b6 kemudian dilakukan perhitungan nilai matriks (baris kali kolom) dan kemudian hasil perkalian tersebut disimpan pada variabel c1, c2, c3, c4, c5 dan c6.

Hasil program di atas sebagai berikut:
