Random Matrix Generator Kev xaiv
Sau tag nrho matrix cov ntsiab lus nrog random tus lej. Sau tsuas yog kab pheeb ces kaum nrog random tus lej. Sau qhov chaw saum kab pheeb ces kaum nrog random tus lej. Sau qhov chaw hauv qab kab pheeb ces kaum nrog random tus lej.
Tom qab ntawd, koj ua li cas los tsim ib lub matrix?
Rau tsim ib array nrog plaub lub ntsiab lus nyob rau hauv ib kab, cais cov ntsiab lus nrog ib qho comma (,) lossis qhov chaw. Hom no array yog kab vector. Rau tsim ib tug matrix uas muaj ntau kab, cais cov kab nrog semicolons. Lwm tus txoj kev los tsim ib tug matrix yog siv ib txoj haujlwm, xws li ib qho, xoom, lossis rand.
Tom qab ntawd, lo lus nug yog, yuav ua li cas koj tsim ib qho kev sib tw hauv Matlab? Tsim Arrays ntawm Random Numbers
- r1 = rand(1000, 1); r1 yog 1000-by-1 kab vector uas muaj cov lej tiag tiag uas tau kos los ntawm kev faib khoom sib xws.
- r2 = randi(10, 1000, 1); r2 yog 1000-by-1 kab vector uas muaj cov lej suav tau los ntawm kev faib tawm tsis sib xws uas nws qhov ntau yog 1, 2,, 10.
- r3 = randn(1000, 1);
- r4 = randperm(15, 5);
Raws li txoj cai, koj yuav ua li cas thiaj tsim tau ib qho random matrix hauv R?
Yuav ua li cas los tsim random binary matrices hauv R
- Siv cov haujlwm runif los tsim cov lej sib txawv ntawm 0 thiab 1, thiab hloov mus rau tag nrho cov lej ze tshaj plaws.
- Siv ifelse ntawm cov zis ntawm runif, thiab muab 0 yog tias nws qis dua 0.5, thiab 1 lwm yam.
- Siv rbinom muaj nuj nqi los ua piv txwv los ntawm kev faib tawm binomial nrog qhov loj ntawm 1 thiab qhov tshwm sim 0.5.
Yuav ua li cas koj tsim ib tug random matrix nyob rau hauv python?
Rau tsim a matrix ntawm random cov lej hauv python , kev daws teeb meem yog siv numpy muaj nuj nqi randint, piv txwv: 1D matrix nrog random tus lej ntawm 0 thiab 9: Matrix (2, 3) ib random integers ntawm 0 thiab 9. Matrix (4, 4) ib random integers ntawm 0 thiab 1.
