Order of a Matrix Ib tug ob-dimensional matrix yeej muaj cov kab uas yog denoted los ntawm (m) thiab ib tug xov tooj ntawm kab denoted los ntawm (n).
Koj txhais li cas ib kab ntawm matrix?
Nws yog qee zaum yuav tsum tau xa mus rau ib kab lossis kem ntawm matrix. Cov kab lossis kab vectors no yog sawv cev los ntawm ib tsab ntawv sau tus lej qis hauv boldface font Piv txwv li, jth kab vector nyob rau saum toj 4 × 3 matrix X yuav raug sau ua ������. Ib square matrix muaj tib cov kab ua ke.
kab hauv matrix yog dab tsi?
Tus kab kab rov tav thiab ntsug ntawm kev nkag hauvtus matrix yog hu ua kab thiab kab, ntsig txog. Qhov loj ntawm lub matrix yog txhais los ntawm tus naj npawb ntawm kab thiab kab uas nws muaj. Lub matrix nrog m kab thiab n kab yog hu ua m × n matrix los yog m -by-n matrix, thaum m thiab n yog hu ua nws qhov ntev.
Koj sawv cev li cas rau matrix?
Muaj ntau txoj hauv kev los sawv cev rau matrix cim. Qhov yooj yim tshaj plaws yog siv ib tsab ntawv boldface, xws li A, B, lossis C. Yog li, A yuav sawv cev rau 2 x 4 matrix, raws li qhia hauv qab no. Cov ntawv sau no qhia tias A yog matrix nrog 2 kab thiab 4 kab.
Cov ntsiab lus ntawm matrix txhais li cas?
Lub caij ntawm matrix feem ntau txhais tau los ntawm ib tsab ntawv me ntawm cov tsiaj ntawv nrog rau ob lub ntsiab lusThawj cov lus qhia qhia cov lej thiab tus thib ob qhia tus lej ntawm kem. Txhua tus lej lossis kev ua haujlwm aij uas yog cov ntsiab lus ntawm matrix yog nyob rau hauv cov kab ke.
