Seidel-Gauss. tikanga ao

Seidel tikanga (te ingoa tuarua - Gauss-Seidel) - ko te tikanga matarohia ao e te mea e taea ki te whakaoti i te pūnaha ngā o whārite rārangi. Na ka kōrero tatou e pā ana ki tenei i roto i te taipitopito atu.

Ko te ngako o te

Tenei tikanga ko te ahua o te whakarereke māmā o te tikanga Jacobi. Te auaha takoto i roto i te meka e te uara hou ⁽ⁱ⁾ whakamahia tonu ki runga ki te taenga, a kihai i muri i te whitiauau muri. I tua atu, āta tāutuhia ngā o pūtahitanga me te mutunga, te tūkino o e e arahi ki te whakautu hē o te whārite. Seidel tikanga, he tauira o e kua hoatu e matou i roto i te pikitia, e kore anake e ohie te tukanga whakatau, engari whakatere hoki i te reira. Na reira, kei te kaha whakamahia reira e hötaka ki te hanga rongoā me ngā pūnaha matatini.

tikanga Seidel. "Pascal"

Tetahi o te kaihātepe kore he kahore tātai pāngarau me whārite. Tenei te tikanga e te kaha whakamahia Seidel tikanga i roto i te "Pascal" ki te riro wheako ki te āhuatanga taketake o te lōpoti. titiro reira tino ohie: hanga te hōtaka he whārangi hou o te pepa i te whārite tāuru tīmatanga huru me tona rohe, a ka whakamārama te āhuatanga tango anō (i raro ki te wātea), whakamātautau ka whakaritea mō te hototahi. Ki te he reira pai, te hātepe whakatau putanga iho, a muri anake i te mutunga o nga pakiaka. Whārite e taea ngā rave rahi ngā wāhanga rongoā, ia o nei he ona ake hātepe, wāhanga e hiahiatia ana, ngā āhuatanga whakawhiti me te tātai taketake. anake i roto i te reo Ingarihi tenei katoa i tuhituhia, i waho te analogs taea. Ka whakaaturia te otinga o te whārite i roto i te puka o te tātai rite-hanga maha ranei i muri ia koutou e whakaora raraunga katoa.

"C ++"

hoki whānui te whakamahia Seidel tikanga i roto i "C ++", engari he tino rerekē atu i te "Pascal" konei katoa. Te whārite i roto i te "C ++" e kore e timata ki te tikanga o te raruraru katoa, engari ki te mutunga o nga tikanga, whakaritea nei i roto i te toru ranei wha ngā wāhanga, me te hua putanga whakamutunga. Next, akoranga i whakaritea o te whakaoti ano i te tikanga o tenei tikanga, whakaahua i roto i te taipitopito katoa o te unknown, a ka ahu mai i te tātai ki te whakamatau i te öritetanga i waenganui i nga hua e rua o te whārite. Ko te huru ko e ia uara o te mua he tika ki te whakatutuki heke mai. Kei te whakahaeretia hoki Accounts i Ingarihi, e kore e taea te whakakapi. "C ++" nui atu uaua "Pascal", na, kahore he te matauranga taketake, kia kore e whakamahia te reira te tīmatanga.

Hei whakarāpopoto

Na Seidel tikanga - ko te ara motuhake e e taea e koe te whakaoti i te pūnaha o ngā whārite rārangi o tetahi whīwhiwhi. Nuinga maha ko reira te pūtake mō ngā hōtaka pērā i "Pascal" me "C ++". Tenei ahua o whakarerekē ake te tikanga Jacobi, e faaore te kōwhiringa o te whakamahi i tātai atu, engari he mārama pūtahitanga me katinga tikanga. paearu tino tautuhia faaohie mahi te tukanga katoa, kia rite ki i roto i te take o te tupuraa-kore o tetahi o nga tikanga o te hōtaka, ahakoa ranei "Pascal" ranei "C ++", kore noa ki te whakatutuki atu i te raruraru.
