Matritsani ko'paytirish qoidalaridan foydalanish qadamlari

Agar birinchi matritsaning ustunlar soni ikkinchi matritsaning satrlariga teng bo'lsa, matritsani ko'paytirish belgilanadi.

$$\left(\begin{matrix}1&2&3\\4&5&6\\7&8&9\end{matrix}\right)\left(\begin{matrix}9&8&7\\6&5&4\\3&2&1\end{matrix}\right)$$

Birinchi matritsadagi birinchi satrning har bir elementini ikkinchi matritsadagi birinchi ustunining tegishli elementiga ko'paytirish, soʻngra koʻpaytma matritsasidagi birinchi satr, birinchi ustunida elementni olish uchun ushbu hosilalarni qo'shish.

$$\left(\begin{matrix}9+2\times 6+3\times 3&&\\&&\\&&\end{matrix}\right)$$

Koʻpaytma matritsasining qoldiq elementlari bir xil yo'l bilan topilgan.

$$\left(\begin{matrix}9+2\times 6+3\times 3&8+2\times 5+3\times 2&7+2\times 4+3\\4\times 9+5\times 6+6\times 3&4\times 8+5\times 5+6\times 2&4\times 7+5\times 4+6\\7\times 9+8\times 6+9\times 3&7\times 8+8\times 5+9\times 2&7\times 7+8\times 4+9\end{matrix}\right)$$

Har bir elementni alohida shartlarga ko'paytirish orqali qisqartirish.

$$\left(\begin{matrix}9+12+9&8+10+6&7+8+3\\36+30+18&32+25+12&28+20+6\\63+48+27&56+40+18&49+32+9\end{matrix}\right)$$

Matritsaning har bir elementini jamlash.

$$\left(\begin{matrix}30&24&18\\84&69&54\\138&114&90\end{matrix}\right)$$
