Ntchito yothandiza ndi kupeza masanjidwewo osiyanitsidwa

Masanjidwewo - tebulo, wodzala ndi akonzedwa ena a manambala mu dongosolo linalake. Mawu amenewa anayamba kwambiri British wasayansi ongolankhula James Sylvester. Iye ndi m'modzi wa omwe adayambitsa ndi chiphunzitso cha ntchito zinthu izi masamu.

Pakali pano, akhala chimagwiritsidwa ntchito pa kuwerengetsera zosiyanasiyana, zomwe ndi zochokera njira monga Mwachitsanzo, kupeza masanjidwewo osiyanitsidwa ku nthambi zosiyanasiyana za zochita za anthu. njira zachokera kudziwa magawo osadziwika kachitidwe zosiyanasiyana maikwezhoni ndipo kawirikawiri amagwiritsidwa ntchito pa kuwerengetsera chuma.

Pali zotsatirazi milandu wapadera izi zigawo masamu: choncho m'munsi, mzati, ziro, lalikulu, opendekera, osakwatiwa. Lowercase tichipeza mzere umodzi wokha wa zinthu, ndi mzati - kwa ndime imodzi manambala. Ziro - onse a zanyengo wofanana 0. The lalikulu masamu a amafotokozera chiwerengero cha mizati wofanana ndi chiwerengero cha mizere. Nayenso, mu opendekera, yomwe ili yaikulu opendekera zinthu wosiyana "0", ndi zina zonse za izo ayenera kukhala wolingana "0". Umunthu - ndi subspecies ya masanjidwewo opendekera. Iye yekha "1" lili waukulu opendekera.

Zitsanzo za mawerengetsedwe:

m'mene: A _K - ndi generic akuti, ndi _ij - zinthu,

(A) 2-TH kuti;

(B) - choncho m'munsi;

(A) -3-TH kuti;

(G) - Chitsanzo 2-TH kuti wagawo tebulo;

Komanso, pali masanjidwewo osiyanitsidwa, kutanthauzira chimene chiri motere. Pamene kuchulukitsa ndi tebulo choyambirira cha unit maganizo analandira. A zosiyanasiyana njira kuti amalola kupeza masanjidwewo osiyanitsidwa. Losavuta awa zachokera tanthauzo la determinant ndi cofactors (nthawi zina amatchedwa determinant ndi).

The determinant a masanjidwewo ndi kuwonetsera kwa _{11 22} kutanthauza _{12 21,} iwo anasonyeza motere: | A |. Chilinganizo pamwamba chomveka kwa tebulo monga mwa dongosolo chachiwiri. chilinganizo kulikonse kwa determinants wa mawerengetsedwe dongosolo apamwamba. Lamulo chikhalidwe cha kuli determinant ndi - tebulo ayenera kukhala lalikulu. Zochita izi mchitidwe mfundo imeneyi nthawi zambiri ntchito mu ndondomeko monga kupeza osiyanitsidwa masanjidwewo.

The chigawo chachiwiri chofunika kuti angagwiritsidwe ntchito kupeza mfundo ya zanyengo ndi cofactor. Iwo masamu mfundo: _ij A = (- 1) ^{i + J} * M _ij, mmene M - yaing'ono. Kwenikweni - izo ndi determinant zina, sipangakhalenso akamagwira conceptually kuchotsa motsogozana ndime imene amafotokozera yogwira ili. Mwachitsanzo, tebulo, monga mwa dongosolo chachiwiri, chomwe chili kale m'lembali, mu chipinda ₁₁ yothandizana algebraic mchitidwe ₂₂ a.

Kupeza masanjidwewo osiyanitsidwa imagwiridwa ndi mbali 3. Gawo loyamba limanenedwa determinants. Mu sitepe yotsatira - cofactors onse, amene ndiye analemba mogwirizana ndi zolozera ake, ndipo likukhalira tebulo cofactors. Pa gawo chomaliza cha osiyanitsidwa masanjidwewo akamagwira kupeza zomwe malekezero kuchulukitsa lililonse kuwonjezapo algebraic mu determinant lapansi.

The masanjidwewo zambiri ntchito ntchito kuwerengetsera zachuma. Ndi thandizo lawo, inu mosavuta ndipo mwamsanga pokonza yambiri zambiri. Pankhaniyi, zotsatira Adzaperekedwa ku yosavuta kuzindikira mawonekedwe.

Wina dera zochita za anthu, imene masanjidwewo komanso anapeza ntchito kwambiri - ichi kayeseleledwe 3D-mafano. Zida izi Integrated mu phukusi ano chifukwa kukhazikitsa 3D-zitsanzo ndi kulola okonza msanga molondola kuchita kuwerengetsera zofunika. Nthumwi wotchuka kwambiri m'magulu otere ndi COMPASS-3D.

pulogalamu ina imene integrates zida kugwira kuwerengetsera amenewa, ndi Microsoft Office, ndipo makamaka - spreadsheet pulogalamu kupambana.
