Yuav Siv Gaussian Elimination li cas los daws cov txheej txheem ntawm kev sib npaug

  1. Koj tuaj yeem sib npaug txhua kab los ntawm qhov tsis tu ncua (tsis yog xoom). multiplies kab peb los ntawm -2 muab koj ib kab tshiab peb.
  2. Koj tuaj yeem hloov ob kab. swaps kab ib thiab ob.
  3. Koj tuaj yeem ntxiv ob kab ua ke. ntxiv kab ib thiab ob thiab sau nws hauv row ob.

Tom qab ntawd, Gaussian tshem tawm ua haujlwm li cas?

Loosely hais lus, Gaussian tshem tawm ua haujlwm los ntawm sab saum toj mus rau hauv, tsim ib tug matrix nyob rau hauv echelon daim ntawv, whereas Gauss -Jordan tshem tawm txuas ntxiv qhov twg Gaussian sab laug los ntawm ces ua hauj lwm los ntawm hauv qab mus rau tsim ib tug matrix nyob rau hauv txo echelon daim ntawv. Cov txheej txheem yuav piav qhia hauv qhov piv txwv hauv qab no.

Tsis tas li ntawd, Cramer txoj cai matrices yog dab tsi? Cramer Txoj Cai rau 2 × 2 System (nrog ob qhov sib txawv) Cramer Txoj Cai yog lwm txoj hauv kev uas tuaj yeem daws cov kab ke ntawm cov kab zauv sib npaug siv cov kev txiav txim. Nyob rau hauv cov nqe lus ntawm notations, a matrix yog ib qho array ntawm cov lej uas tau kaw los ntawm cov square brackets thaum tus txiav txim yog ib qho array ntawm cov lej uas tau muab los ntawm ob txoj kab ntsug.

Qhov thib ob, lub hom phiaj ntawm Gaussian tshem tawm yog dab tsi?

Gaussian tshem tawm . Los ntawm Wikipedia, dawb encyclopedia. Gaussian tshem tawm , tseem hu ua kab txo qis, yog ib qho algorithm nyob rau hauv linear algebra rau kev daws ib qho system ntawm linear equations. Nws yog feem ntau to taub raws li ib theem zuj zus ntawm kev ua hauj lwm ua nyob rau hauv sib xws matrix ntawm coefficients.

Dab tsi yog qhov txawv ntawm Gaussian thiab Gauss Jordan tshem tawm?

3 Teb. Gaussian Elimination pab muab ib tug matrix nyob rau hauv kab echelon daim ntawv, thaum Gauss - Jordan Elimination muab ib tug matrix nyob rau hauv txo kab echelon daim ntawv. Rau cov tshuab me me (lossis ntawm tes), feem ntau nws yooj yim dua los siv Gauss - Jordan tshem tawm thiab qhia meej meej rau txhua qhov sib txawv uas sawv cev hauv matrix system.
