Syntax

R = nctrnd(V,DELTA)
R = nctrnd(V,DELTA,m,n,...)
R = nctrnd(V,DELTA,[m,n,...])

Description

R = nctrnd(V,DELTA)returns a matrix of random numbers chosen from the noncentral T distribution using the corresponding degrees of freedom inVand noncentrality parameters inDELTA.VandDELTA可以是向量,矩阵,或多维arra吗ys. A scalar input forVorDELTAis expanded to a constant array with the same dimensions as the other input.

R = nctrnd(V,DELTA,m,n,...)orR = nctrnd(V,DELTA,[m,n,...])generates anm-by-n-by-... array. TheV,DELTAparameters can each be scalars or arrays of the same size asR.

Examples

nctrnd(10,1,5,1) ans = 1.6576 1.0617 1.4491 0.2930 3.6297
