Canonical Daim ntawv. Cov txheej txheem uas yog siv los sawv cev rau cov chaw ua lej lossis matrix nyob rau hauv nws tus qauv daim ntawv (los yog lej qhia) yog hu ua canonical daim ntawv. Daim duab peb sab, Jordan canonical daim ntawv thiab kab echelon daim ntawv yog qee qhov loj canonical Cov ntawv hauv Linear Algebra.

Ntawm no, lub ntsiab lus ntawm daim ntawv canonical yog dab tsi?

A canonical daim ntawv yog ib feem ntawm ib pawg ntawm cov neeg sawv cev ntawm equivalence chav kawm ntawm daim ntawv xws li tias muaj kev ua haujlwm lossis txheej txheem uas ua haujlwm txhua lub ntsiab lus ntawm txhua chav kawm sib npaug mus rau qhov ntawd, qhov canonical daim ntawv ntawm cov chav kawm sib npaug.

Ib tug kuj yuav nug, dab tsi yog daim ntawv ntawm ib tug matrix? Daim ntawv li qub (rau matrices ) Cov ib txwm daim ntawv ntawm ib tug matrix yog a matrix ntawm qhov tshwj xeeb ua ntej daim ntawv tau los ntawm kev hloov pauv ntawm ib hom tshuaj. (Ntawm no qhia txog cov txheej txheem tag nrho matrices ntawm kab thiab kab nrog coefficients hauv.)

Tsis tas li ntawd, Canonical txhais li cas hauv lej?

Hauv lej thiab computer science, a canonical , normal, or standard form of a lej object yog ib txoj hauv kev los nthuav qhia qhov khoom ntawd li a lej kev qhia. Feem ntau, nws yog ib qho uas muab qhov yooj yim tshaj plaws sawv cev ntawm ib yam khoom thiab uas tso cai rau nws los txheeb xyuas nyob rau hauv ib tug tshwj xeeb txoj kev.

Qhov piv txwv canonical yog dab tsi?

A canonical URL yog qhov URL ntawm nplooj ntawv uas Google xav tias yog tus sawv cev feem ntau los ntawm cov nplooj ntawv sib npaug ntawm koj qhov chaw. Rau piv txwv , yog tias koj muaj URLs rau tib nplooj ntawv (rau piv txwv : piv txwv .com? hnav = 1234 thiab piv txwv .com/dresses/1234), Google xaiv ib tug li canonical.
