Indicator for sampling with replacement, specified as eitherfalseortrue. Example:randsample(10,2,true)returns two values with replacement from the integers1to10. Data Types:logical w—Sampling weights ones(n,1)(default) |vector of nonnegative scalar values ...
. 有关randperm的命令 = randperm(N)%表示将1:N的N个数打乱顺序 P = randperm (N,K) %从1:N随机选择K个数,不能重复 To allow repeated values in the selection, sometimes referred to as sampling with replacement, use RANDI(N,1,K). 此外,在官方教程中还提到了,如果要求重复,可以使用 P =...
Example:randsample(20,10)returns a vector of10values sampled uniformly at random, without replacement, from the integers1to20. Data Types:single|double Indicator for sampling with replacement, specified as eitherfalseortrue. Example:randsample(10,2,true)returns two values with replacement from the ...
jackstat = jackknife(jackfun,X,Y,...)accepts additional arguments to be supplied as inputs tojackfun. They may be scalars, column vectors, or matrices.jackknifecreates each jackknife sample by sampling with replacement from the rows of the non-scalar data arguments (these must have the same...
For selecting weighted samples without replacement,datasampleuses the algorithm of Wong and Easton[1]. Alternative Functionality You can userandiorrandpermto generate indices for random sampling with or without replacement, respectively. However,datasamplecan be more convenient to use because it samples ...
