Sissejuhatus maatriksi korrutamisse C programmeerimisel
Artiklis C Maatriksi korrutamise programmeerimine on maatriks ruudustik, mida kasutatakse andmete salvestamiseks struktureeritud vormingus. Sageli kasutatakse seda koos tabeliga, kus andmed on esitatud horisontaalsete ridade ja vertikaalsete veergudena. Maatriksit kasutatakse sageli programmeerimiskeeltes ja andmete esitamiseks graafilises struktuuris. Kui kasutaja soovib programmeerida kahte maatriksit korrutama, liitma, lahutama ja jagama, tuleks kõigepealt deklareerida maatriksi järjekord. Kui maatriksi järjekord on deklareeritud esimese ja teise maatriksi jaoks, peab kasutaja sisestama maatriksite elemendid (sisendi). Kui maatriksi järjekord ei ole üksteisega proportsionaalne, kuvatakse tõrketeade, mille programmeerija implanteerib tingimuste avaldusse. Kui maatriks sisaldab ainult ühte rida, nimetatakse seda reavektoriks ja kui see sisaldab ainult ühte veergu, siis nimetatakse seda veeruvektoriks.
Maatriksit, mis sisaldab sama arvu ridu ja veerge, nimetatakse ruutmaatriksiks. Maatriksit kasutatakse seotud andmete rühma salvestamiseks. Mõnda programmeerimiskeelt kasutatakse maatriksite toetamiseks andmetüübina, mis pakub suuremat paindlikkust kui staatiline massiiv. Väärtuste maatriksisse salvestamise asemel saab seda salvestada individuaalse muutujana, programm pääseb andmetele tõhusamalt juurde ja saab neid operatsioone teostada. C programmeerimisel maatriks korrutatakse massiivide, funktsioonide, osutite abil. Seetõttu arutame koos vooskeemiga maatriksi korrutamise algoritmi, mida saab kasutada programmeerimiskoodi kirjutamiseks maatriksi 3x3 korrutamiseks kõrgetasemelises keeles. See üksikasjalik selgitus aitab teil maatriksi korrutamise töömehhanismi analüüsida ja aitab mõista, kuidas koodi kirjutada.
C-programmeerimismaatriksi korrutamise algoritm
1. samm: käivitage programm.
2. samm: sisestage esimese maatriksi (a) rida ja veerg.
3. samm: sisestage teise maatriksi (b) rida ja veerg.
4. samm: sisestage esimese maatriksi elemendid.
5. samm: sisestage teise maatriksi (b) elemendid.
6. samm: printige maatriksi kujul esimese (a) maatriksi elemendid.
7. samm: printige maatriksi kujul teise (b) maatriksi elemendid.
8. samm: seadke silmus kuni rida.
9. samm: määrake sisemine silmus kolonni üles.
10. samm: määrake kolonni teine sisemine silmus.
11. samm: korrutage esimene (a) ja teine (b) maatriks ja hoidke element kolmandas maatriksis (c)
12. samm: printige lõplik maatriks.
13. samm: peatage programm.

C programmeerimismaatriksi korrutamise töö
- Ülaltoodud programmis oleme põhimeetodi sees muutujad ja massiivid algatanud täisarvulise (int) andmetüübiga.
- Pärast initsialiseerimisosa saame kasutajalt maatriksi järjekorra esimese maatriksi jaoks, seejärel peab kasutaja samal ajal deklareerima teise maatriksi järjekorra.
- Kui maatriksite järjekord on deklareeritud, siis tingimusosa ka täidetakse, programm jätkub ainult siis, kui tellimus vastab tingimusele või vastasel juhul programm lõpetatakse või peatatakse selles osas.
- Kui tingimus on täidetud, peab kasutaja sisestama maatriksielemendid sisenditena töö ajal.
- Kasutaja sisestatud maatriksi järgi arvutatakse korrutamine.
- Ülaltoodud maatriksprogramm on lihtne ja suudab arvutada värskenduse 25 × 25, seega saame massiivis lihtsalt redigeerida vajalike arvudeni.
C-programmeerimise maatriksi korrutamise eelised
- C-programmeerimiskeel toetab maatriksit andmetüübina ja pakub suuremat paindlikkust. Samuti kulutab töötlemine vähem mälu.
- Salvestades väärtusi maatriksis, mitte üksikute muutujatena, pääseb C-programm andmetele tõhusamalt juurde ja saab neid operatsioone teostada.
- Objektide pöörlemise kohta on lihtsam teavet hankida ja C-programmis on neid ka hõlbus käsitseda.
Järeldus
Maatrikskorrutamist kasutatakse programmides korduvalt graafilise andmestruktuuri esitamiseks, mida kasutatakse mitmete vektorite salvestamiseks, ning seda kasutatakse paljudes rakendustes, näiteks lineaarvõrrandite lahendamisel ja mujal. Maatriksite korrutamisel minimaalse arvu toimingute abil on tehtud palju uuringuid.
