Tono Practical me te kimi i te kopu kōaro

Matrix - he tepu, ki tonu nei i te te huinga etahi o tau i roto i te tetahi raupapa. tapa tenei wā i tino pūtaiao Ingarangi ariā James Sylvester. Ko ia tetahi o nga kaiwhakatū o te ariā o te tono o enei āhuatanga pāngarau.

Ki te rā, kua whakamahia whānuitia ratou i roto i ngā tātaitanga, i e hāngai ana i runga i te tikanga pērā i, mo te tauira, te kimi i te poukapa kōaro i roto i nga manga ngā o te mahi a te tangata. hāngai ana tēnei tikanga i runga i te whakatau i nga tawhā unknown o ngā pūnaha ngā o whārite me te maha whakamahia i roto i te tātai ōhanga.

He nga take motuhake e whai ake nei enei wae pāngarau: take o raro, he tīwae, kore, tapawha, hauroki, kotahi. Kei pūriki o tetahi anake rarangi o āhuatanga, me te tīwae - o te tīwae kotahi o tau. Zero - katoa o ona āhuatanga rite ki te 0. Ko te tapawha pāngarau o te tau huānga o tīwae rite ki te maha o ngā rārangi. I roto i te tahuri, i roto i te hauroki, kei runga i nga mea timatanga hauroki matua rerekē i "0", a kia kia rite ki "0" te toenga o taua mea. Tuakiri - Ko te momo o te kopu hauroki. Ia anake "1" Kei te i runga i te hauroki matua.

Tauira o tāhū,:

ai: He _k - he wā kano, he _ij - huānga,

(A) kia 2-th;

(B) - take o raro;

(A) kia -3-th;

(G) - Tauira 2-th raupapa tepu wae;

Ano, i reira he he kopu kōaro, te whakamāramatanga o te mea e whai ake. A, no te whakanuia e te tepu taketake o te wae urupare whiwhi te. He momo o ngā rautaki e faati'a ai te rapu i te kopu kōaro. hāngai ana te māmā o enei i runga i te whakamāramatanga o te tokoingoa me cofactors (hoki ētahi wā ka kīia ki rite te tokoingoa).

Ko te tokoingoa o te kopu ko te faaiteraa o te ₁₁ i te ₂₂ -a ₁₂ he _21, kua tohua i te reira e whai ake: | A |. he tika hoki te tepu rite ki te rua i te tikanga te tātai i runga ake. Tetahi tātai mo te tikanga e o te tāhū, o te tikanga teitei. huru obligatory mo te oraraa o te tokoingoa - kia tapawha te tepu. I roto i te mahi, kei te tino maha whakamahia tenei huānga o tenei ariā i roto i te tukanga, pērā i te kimi i te kopu kōaro.

Ko te wāhanga nui tuarua e taea te whakamahi ki te kitea te uara o ona āhuatanga ko te cofactor. Kei te tatau te reira e te tātai: He _ij = (- 1) ^{+ i j} * M _ij, ai M - he iti. Tino - Ko reira he tokoingoa atu, e taea te whiwhi e conceptually tango te haupae me te tīwae roto i kei te huānga hohe te. Hei tauira, mo te tepu, rite ki te rua o nga tikanga, whakaaturia nei i mua i roto i te kuputuhi, i roto i te pūtau ₁₁ Ka kīnaki i huānga taurangi ₂₂ he.

Kimi mai i tētahi kopu kōaro whakamana i roto i te 3 ngā wāhanga. tautuhi ana te atamira tuatahi te whakatika. I roto i te taahiraa i muri mai - i te cofactors katoa, e ka tuhia i runga i ona taupū, a huri i te reira i roto i nga cofactors tepu. I te wā whakamutunga o te kopu kōaro whiwhi i te kitenga e pito whakanuia ia tāpiritanga taurangi i roto i te tokoingoa.

Ko te kopu tino whakamahia nuitia whakamahia i roto i te tātai ōhanga. Ki te to ratou awhina, ngāwari me hohoro koutou e taea e tukatuka nui o ngā mōhiohio. I roto i tenei take, ka te hua mutunga kia aroaro i roto i te ngāwari ki te perception o puka.

Ko tētahi atu wāhi o te mahi a te tangata, i roto i nei i kitea ano te kopu whakamahi nui - tenei whaihanga 3D-whakapakoko. E ngātahi ēnei taputapu ki pōkai hou mo te whakatinanatanga o 3D-tauira, me tukua kaihoahoa ki hohoro a tika te mahi i te tātai tika. Ko te māngai tino nui o taua pūnaha ko te kāpehu-3D.

Tētahi atu hōtaka, e whakauru ana te taputapu ki te kawe i roto i taua tātainga, ko Microsoft Office, me te ake āta - hōtaka ripakaute Excel.
