Matritsani ko'paytirish qoidalaridan foydalanish qadamlari

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

$$\left(\begin{matrix}1&1&1\\0&2&3\\5&5&1\end{matrix}\right)\left(\begin{matrix}\frac{13}{8}&-\frac{1}{2}&-\frac{1}{8}\\-\frac{15}{8}&\frac{1}{2}&\frac{3}{8}\\\frac{5}{4}&0&-\frac{1}{4}\end{matrix}\right)$$

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.

$$\left(\begin{matrix}\frac{13}{8}-\frac{15}{8}+\frac{5}{4}&&\\&&\\&&\end{matrix}\right)$$

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

$$\left(\begin{matrix}\frac{13}{8}-\frac{15}{8}+\frac{5}{4}&\frac{-1+1}{2}&-\frac{1}{8}+\frac{3}{8}-\frac{1}{4}\\2\left(-\frac{15}{8}\right)+3\times \frac{5}{4}&2\times \frac{1}{2}&2\times \frac{3}{8}+3\left(-\frac{1}{4}\right)\\5\times \frac{13}{8}+5\left(-\frac{15}{8}\right)+\frac{5}{4}&5\left(-\frac{1}{2}\right)+5\times \frac{1}{2}&5\left(-\frac{1}{8}\right)+5\times \frac{3}{8}-\frac{1}{4}\end{matrix}\right)$$

Har bir elementni alohida shartlarga ko'paytirish orqali qisqartirish.

$$\left(\begin{matrix}\frac{13}{8}-\frac{15}{8}+\frac{5}{4}&\frac{-1+1}{2}&-\frac{1}{8}+\frac{3}{8}-\frac{1}{4}\\\frac{-15+15}{4}&1&\frac{3-3}{4}\\\frac{65}{8}-\frac{75}{8}+\frac{5}{4}&\frac{-5+5}{2}&-\frac{5}{8}+\frac{15}{8}-\frac{1}{4}\end{matrix}\right)$$

Matritsaning har bir elementini jamlash.

$$\left(\begin{matrix}1&0&0\\0&1&0\\0&0&1\end{matrix}\right)$$
