Peb tuaj yeem ntxiv lossis rho tawm cov lej yog tias lawv qhov ntev yog tib yam. Txhawm rau ntxiv cov matrices, peb tsuas yog ntxiv cov matrix sib txuas ua ke. Txhawm rau rho tawm matrices, peb tsuas yog rho tawm cov lej sib txuas ua ke.
Koj ntxiv thiab rho cov matrices li cas?
A matrix tsuas yog muab ntxiv rau (lossis rho tawm los ntawm) lwm qhov matrix yog tias ob lub matrices muaj qhov sib npaug. Txhawm rau ntxiv ob qhov matrices, tsuas yog ntxiv cov khoom nkag, thiab tso cov lej no rau hauv txoj haujlwm sib xws hauv matrix uas tau tshwm sim.
Koj puas tuaj yeem rho tus lej los ntawm matrix?
Kev rho tawm ntawm matrix yog ua tau los ntawm kev rho tawm lub ntsiab ntawm lwm qhov matrix yog tias lawv muaj tib qhov kev txiav txim Qhov tshiab matrix no yog qhov sib txawv ntawm cov saum toj no ob matrices. Yog li, qhov sib txawv ntawm ob lub matrices yog tau los ntawm kev rho tawm cov ntsiab lus ntawm cov matrices muab.
Koj puas tuaj yeem ntxiv lossis rho tawm cov lej sib txawv?
Kuv yuav tsum hais meej tias txhawm rau ntxiv lossis rho tawm ob qhov matrices, lawv yuav tsum muaj qhov loj me lossis qhov ntev. Txwv tsis pub, peb txiav txim siab tias cov lej (ntxiv) lossis qhov sib txawv (sib rho) ntawm ob lub matrices muaj qhov sib txawv lossis qhov ntev tsis tau txhais!
Koj puas tuaj yeem muab 3x3 thiab 2x3 matrix?
Multiplication of 2x3 and 3x3 matrices is possible and the result matrix is a 2x3 matrix.
