ਮੈਟ੍ਰਿਕਸ (ਗਣਿਤ)

ਮੈਟ੍ਰਿਕਸ ਵਿੱਚ ਪਰਤੱਖ ਅੰਕਾਂ ਨੂੰ ਛੋਟਾ ਕਰ ਕੇ ਦਰਸਾਇਆ ਜਾਂਦਾ ਹੈ।

ਹਿਸਾਬ ਵਿੱਚ ਨੰਬਰਾਂ ਦੇ ਸਮਕੋਨੀ ਵਰਤਾਰੇ ਨੂੰ ਮੈਟ੍ਰਿਕਸ (ਜਾਂ ਮੈਟਰਿਕਸ) ਕਹਿੰਦੇ ਹਨ। ਜਿਵੇਂ,

{\begin{bmatrix}1&9&13\\20&55&4\end{bmatrix}}.

ਮੈਟ੍ਰਿਕਸ ਨੂੰ ਅਲਜੈਬਰਾ ਵਿੱਚ ਖ਼ਾਸ ਅਤੇ ਮੁਸ਼ਕਲ ਬਦਲਾਵਾਂ ਨੂੰ ਸੌਖੇ ਤਰੀਕੇ ਨਾਲ ਦਰਸਾਉਣ ਲਈ ਵਰਤਿਆ ਜਾਂਦਾ ਹੈ।

ਜਮ੍ਹਾ

${\begin{bmatrix}1&3&1\\1&0&0\end{bmatrix}}+{\begin{bmatrix}0&0&5\\7&5&0\end{bmatrix}}={\begin{bmatrix}1+0&3+0&1+5\\1+7&0+5&0+0\end{bmatrix}}={\begin{bmatrix}1&3&6\\8&5&0\end{bmatrix}}$

ਗੁਣਾ

$2\cdot {\begin{bmatrix}1&8&-3\\4&-2&5\end{bmatrix}}={\begin{bmatrix}2\cdot 1&2\cdot 8&2\cdot -3\\2\cdot 4&2\cdot -2&2\cdot 5\end{bmatrix}}={\begin{bmatrix}2&16&-6\\8&-4&10\end{bmatrix}}$

ਪਿਛੋਕੜ

ਸਭ ਤੋਂ ਪਹਿਲਾਂ ਇਹਨਾਂ ਨੂੰ ਚੀਨੀ ਹਿਸਾਬਕਾਰ, ਹੂ ਸਾਂਗ ਸੁਆਂਗ ਸੂ ਨੇ ਵਰਤਿਆ। ਫ਼ਿਰ ਇਹਨਾਂ ਨੂੰ ਹੀਜ਼ਨਬਰਗ, ਪਾਸਕਲ ਆਦਿ ਵਰਗੇ ਵਿਗਿਆਨੀਆਂ ਨੇ ਭੀ ਅਪਣੀ ਸੋਧ ਵਿੱਚ ਵਰਤਿਆ।
