frnd - F random numbers

Syntax

R = frnd(V1,V2)
R = frnd(V1,V2,v)
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.

R = frnd(V1,V2,v) generates random numbers from the F distribution with parameters V1 and V2, where v is a row vector. If v is a 1-by-2 vector, R is a matrix with v(1) rows and v(2) columns. If v is 1-by-n, R is an n-dimensional array.

R = frnd(V1,V2,m,n) generates random numbers from the F distribution with parameters V1 and V2, where scalars m and n are the row and column dimensions of 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
