frnd

F random numbers

Syntax

R = frnd(V1,V2)
R = frnd(V1,V2,m,n,...)
R = frnd(V1,V2,[m,n,...])

Description

R = frnd(V1,V2) generates random numbers from the F distribution with numerator degrees of freedom V1 and denominator degrees of freedom V2. V1 and V2 can be vectors, matrices, or multidimensional arrays that all have the same size. A scalar input for V1 or V2 is expanded to a constant array with the same dimensions as the other input. V1 and V2 parameters must contain real positive values.

R = frnd(V1,V2,m,n,...) or R = frnd(V1,V2,[m,n,...]) generates an m-by-n-by-... array containing random numbers from the F distribution with parameters V1 and V2. V1 and V2 can each be scalars or arrays of the same size as R.

Examples

n1 = frnd(1:6,1:6)
n1 =
  0.0022  0.3121  3.0528  0.3189  0.2715  0.9539

n2 = frnd(2,2,[2 3])
n2 =
  0.3186  0.9727  3.0268
  0.2052 148.5816  0.2191

n3 = frnd([1 2 3;4 5 6],1,2,3)
n3 =
  0.6233  0.2322  31.5458
  2.5848  0.2121  4.4955
