UMatlab

Ixazululiwe: iseli ukuze ihlelwe

Impela, Ake siqale ukubhala indatshana ehlobene nokuthi “Ukuguqula Iseli libe I-Array ku-MATLAB”, sigxile esingenisweni sesihloko, isixazululo, incazelo yekhodi yesinyathelo nesinyathelo, nokugqamisa imitapo yolwazi ethile ye-MATLAB noma imisebenzi ehilelekile ekuxazululeni le nkinga.

Amalungu afanayo amaseli ku-MATLAB zisebenze njengeziqukathi zedatha - zingabamba idatha yezinhlobo nosayizi abahlukahlukene. Nokho, kunezimo lapho sidinga ukuguqula amalungu afanayo eseli abe amalungu afanayo avamile ukuze kube lula ukukhohlisa nokubala. Ukuguqula amalungu afanayo eseli abe yi-matrix kuyinqubo ebalulekile, ikakhulukazi ekuphatheni amasethi edatha amakhulu.

Kuxazululiwe: shintsha iyunithi yezinhlamvu

Sonke sihlangabezana nezimo ezinhlelweni zeMatlab lapho sidinga ukushintsha izingxenye zeyunithi yezinhlamvu. Kungumsebenzi ojwayelekile ukulungisa iphutha kanye nokwenza ngcono amakhodi ethu. Kodwa siwenza kanjani lo msebenzi usebenze kahle futhi ungahluphi? Yilokho le nkulumo ehlose ukukukhuluma.

Ixazululiwe: iyunithi yezinhlamvu ukuya ku-int

Emkhakheni wezinhlelo zokubala, isihloko esiphindayo esithakaselwayo ukuguqulwa kwezinhlobo zedatha. Ikakhulukazi, ukuguqulwa kwamayunithi ezinhlamvu abe izinombolo. Imvelo ye-MATLAB ihlinzeka ngezindlela eziningi zokufeza lokhu, ngayinye ifanele izimo nezidingo zomhleli. Kuso sonke lesi sihloko, sizocubungula inqubo yokufeza lokhu kuguqulwa okuvama ukubalulekile, sibe sigqamisa imisebenzi ethile ye-MATLAB ehlotshaniswa nalo msebenzi, kanye nencazelo yesinyathelo nesinyathelo yekhodi ehilelekile.

Ixazululiwe: i-radian kuya ku-degree

=============================

Emhlabeni wezibalo nokubala, kusetshenziswa amayunithi ahlukahlukene okulinganisa, okugqamayo phakathi kwawo ama-radians namadigri okulinganisa ama-engeli. Lawa mayunithi amabili kufanele ashintshaniswe ngezikhathi ezithile ngokuya ngesidingo senkinga edinga ukuxazululwa. Esimeni sokuhlela seMatlab, ukuguqulwa kweradian kuya kudigri kungenziwa kusetshenziswa ucezu olulula lwekhodi. Njengabathuthukisi, sivame ukuhlangana nale mfuneko, yingakho ukuqonda umqondo kanye nekhodi yeMatlab ukuze kuhlangatshezwane nalesi sidingo kungaba usizo olukhulu.

Kuxazululiwe: gcina umbhalo


Ukulondoloza amafayela ombhalo kuwumsebenzi ovamile owenziwa kuzinhlelo zokusebenza eziningi zokubala, njengokuhlaziywa kwedatha, ama-algorithms okufunda ngomshini, nokucubungula isignali yedijithali, phakathi kokunye. Ikhono lokugcina, lokufinyelela, kanye nokukhohlisa amasethi edatha amakhulu libalulekile ekuthuthukisweni okuningi kwezobuchwepheshe kanye nezinto ezintsha. Kodwa ngempela siwufeza kanjani lo msebenzi ku-MATLAB, indawo ephezulu yolimi nekhompyutha ethandwa onjiniyela, ososayensi, nonjiniyela emhlabeni wonke? Ake sibhekisise.

Kuxazululiwe: i-factoral

Impela, nasi isibonelo sokuthi le ndatshana ende emayelana ne-factorial eMatlab ingabukeka kanjani:

I-Factorial ingumqondo oyisisekelo nobalulekile kwizibalo. Ngokuvamile, isetshenziswa ematfuba kanye nezibalo, algebra nokuningi. Sizozama ukuthola i-factorial yenombolo sisebenzisa iMatlab, okuwulimi oluhlonishwa kakhulu endaweni yezinombolo zekhompuyutha.

IMatlab, ethuthukiswe yi-MathWorks, inikeza ukusebenza okulula kanye nohlu olubanzi lwamathuluzi ayenza ibe inketho ekhethwayo konjiniyela nocwaningo emhlabeni wonke.

Kuxazululiwe: thola ku-python

Ukuthola Izinto kuPython ngeMatlab

I-Python ingolunye lwezilimi zokuhlela ezisebenza kahle kakhulu zonjiniyela ngenxa yobulula bayo kanye nokusetshenziswa okubanzi. Omunye wemisebenzi iPython ephumelela kakhulu kuyo ukuthola izakhi ngaphakathi kwesakhiwo, njenge-array. Yize iPython inhle kakhulu ekwenzeni lo msebenzi, akubona bonke abathuthukisi abajwayelene nendlela yokwenza lokhu kuPython. Ngakho-ke, lesi sihloko sizogxila ekuchazeni indlela yokusebenzisa iPython ukuthola izakhi, usebenzisa iMatlab ngenxa yesakhiwo sayo sokubhala amakhodi esilula futhi esiqondakala kalula. Sizokufeza lokhu ngokusebenzisa iMatlab ukuze sinikeze isinyathelo ngesinyathelo sekhodi. Sizophinde sichaze iqhaza lemitapo yolwazi nemisebenzi eyahlukene nokuthi ingasetshenziswa kanjani kulo mongo.

Kuxazululiwe: indlela yokwazi uhlobo lwesici

Ukwazi uhlobo lwe-elementi kungakusiza ukuthi udale amawebhusayithi angcono. Lesi sihloko sizokufundisa ukuthi ungazihlonza kanjani izinhlobo ezahlukene zezinto nokuthi ungazisebenzisa kanjani ekwakhiweni kwewebhusayithi yakho.
