I have an array name time with 1 row and 1000 columns. time=[5,6,7,2,8,1,3,9...] I want to call randomly any values from that array. Following is my working algorithm. time2 = any random values from time time3 = any random values from time time4...
先选择Xnew_ks_notsel_ks_sel,然后选择Select from array,再选idx_validation,再点击Invert就会反向选择,意思就是把Xnew_ks_notsel_ks_sel剩下的数据全选上。 To choose the samples of prediction, select the matrix Xnew_ks_notsel_ks_sel again in the “Data matrices in the workspace” group. Use ...
Size of each dimension, specified as integer values. For example, specifying5,3,2generates a 5-by-3-by-2 array of random numbers from the specified probability distribution. If one or more of the input argumentsA,B,C, andDare arrays, then the specified dimensionssz1,...,szNmust match ...
For instance, create a random number stream using a combined multiple recursive generator. s = RandStream('mrg32k3a'); To reposition a stream to a particular substream, set itsSubstreamproperty. For instance, generate random numbers in a loop. Position the random number stream to the beginning...
X = rand returns a random scalar drawn from the uniform distribution in the interval (0,1). X = rand(n) returns an n-by-n matrix of uniformly distributed random numbers. example X = rand(sz1,...,szN) returns an sz1-by-...-by-szN array of random numbers where sz1,...,szN ...
Dimension lengths, returned as a nonnegative integer scalar whendimis a positive integer scalar, a row vector of nonnegative integer scalars whendimis a vector of positive integers, or a 1-by-0 empty array whendimis an empty array. If an element of the specified dimension argument is larger ...

R = corrcoef(A) returns the matrix of correlation coefficients for A, where the columns of A represent random variables and the rows represent observations. example R = corrcoef(A,B) returns coefficients between two random variables A and B. example [R,P] = corrcoef(___) returns the matri...
