Scalars, Vectors thiab Matrices

Ib tug scalar yog tus lej, xws li 3, -5, 0.368, thiab lwm yam, A vector yog ib daim ntawv teev cov lej (yuav ua tau ib kab lossis kab), A matrix yog ib array ntawm tus lej (ib lossis ntau kab, ib lossis ntau kab).

Raws li, qhov sib txawv ntawm matrix thiab vector yog dab tsi?

A matrix tsuas yog ib daim duab plaub ntawm cov lej thiab a vector yog kab (los yog kab) ntawm a matrix . Nyeem ntxiv txog cov ntsiab lus siv tau hauv cov ntaub ntawv Matrices thiab arrays/ cov duab . Tsis tas li, nyeem qee qhov kev xav hauv Wikipedia rau Matrix (lej).

Tsis tas li ntawd, dab tsi yog matrix lub sij hawm vector? Kev sib tw a Vector los ntawm a Matrix . Rau muab ntau ntau ib row vector los ntawm ib kab vector , rov vector yuav tsum muaj cov kab ntau npaum li kem vector muaj kab. Yog tias peb cia Ax = b, ces b yog ib kab m × 1 vector . Hauv lwm lo lus, tus naj npawb ntawm cov kab hauv Adetermines tus naj npawb ntawm kab hauv cov khoom b.

Kuj paub, yog matrix ib vector ntawm vectors?

Nyob rau hauv linear algebra, ib kem vector los yog kab matrix yog mx1 matrix , uas yog, amatrix muaj ib kem ntawm m cov ntsiab lus, Cov txheej ntawm txhua kab cov duab forms ib vector qhov chaw hu ua rowspace, zoo ib yam li txheej ntawm txhua kab cov duab forms ib vector qhov chaw hu ua kem chaw.

Dab tsi yog vector hauv linear algebra?

Lub ntsiab txhais ntawm a vector uas koj kawm hauv linear algebra qhia koj txhua yam koj xav paub txog dab tsi a vector yog nyob rau hauv tej qhov chaw. A vector yog ib qho yooj yim lub ntsiab ntawm a vector qhov chaw, lub sijhawm. Yog li ntawd, hais tias a vector yog ib kem ntawm tus lej, lossis cov khoom geometric nrog qhov loj thiab kev taw qhia, tsis raug.
