A matrix A tuaj yeem muaj ntawm most one inverse. Lub inverse ntawm ib tug invertible matrix yog denoted A-1. Tsis tas li ntawd, thaum lub matrix yog invertible, nws yog inverse, thiab nws inverse tus inverse yog nws tus kheej, (A-1)-1=A. Yog li, muaj feem ntau ib inverse.

Tus lej inversions hauv matrix yog dab tsi?

Inversion suav hauv matrix txhais tau tias yog tus lej ntawm cov khub uas txaus siab rau cov xwm txheej hauv qab no: x₁ ≤ x.

Txhua matrix puas tuaj yeem hloov pauv tau?

A. Tsis yog tag nrho 2 × 2 matrices muaj qhov sib hloov matrix. Yog hais tias tus txiav txim ntawm lub matrix yog xoom, ces nws yuav tsis muaj inverse; lub matrix thiaj li hais tias yog ib qho. Tsuas tsis yog tus lej matrices muaj inverses.

Dab tsi matrix tsis tuaj yeem hloov pauv?

Ib yam lus matrix ua tsis muaj qhov hloov pauv. Txhawm rau nrhiav qhov rov qab ntawm lub square matrix A, koj yuav tsum nrhiav lub matrix A−1 xws li cov khoom ntawm A thiab A−1 yog tus lej matrix.

Is a-1 the inverse matrix?

Tus inverse of a square matrix A, denoted by A^-1, is the matrix yog li cov khoom ntawm A thiab A^{-1 yog tus lej lej. Tus lej matrix uas tau tshwm sim yuav zoo ib yam li matrix A.}
