chi2rnd - Chi-square random numbers

Syntax

R = chi2rnd(V)
R = chi2rnd(V,u)
R = chi2rnd(V,m,n)

Description

R = chi2rnd(V) generates random numbers from the chi-square distribution with degrees of freedom parameters specified by V. V can be a vector, a matrix, or a multidimensional array. R is the same size as V.

R = chi2rnd(V,u) generates an array R of size u containing random numbers from the chi-square distribution with degrees of freedom parameters specified by V, where u is a row vector. If u is a 1-by-2 vector, R is a matrix with u(1) rows and u(2) columns. If u is 1-by-n, R is an n-dimensional array.

R = chi2rnd(V,m,n) generates an m-by-n matrix containing random numbers from the chi-square distribution with degrees of freedom parameter V.

Examples

Note that the first and third commands are the same, but are different from the second command.

r = chi2rnd(1:6)
r =
    0.0037  3.0377  7.8142  0.9021  3.2019  9.0729

r = chi2rnd(6,[1 6])
r =
    6.5249  2.6226  12.2497  3.0388  6.3133  5.0388

r = chi2rnd(1:6,1,6)
r =
  0.7638  6.0955  0.8273  3.2506  1.5469  10.9197
