geornd - Geometric random numbers

Syntax

R = geornd(P)
R = geornd(P,v)
R = geornd(P,m,n)

Description

R = geornd(P) generates geometric random numbers with probability parameter P. P can be a vector, a matrix, or a multidimensional array. The size of R is the size of P. The geometric distribution is useful when you want to model the number of successive failures preceding a success, where the probability of success in any given trial is the constant P.

R = geornd(P,v) generates geometric random numbers with probability parameter P, 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 = geornd(P,m,n) generates geometric random numbers with probability parameter P, where scalars m and n are the row and column dimensions of R.

The parameters in P must lie on the interval [0 1].

Examples

r1 = geornd(1 ./ 2.^(1:6))
r1 =
   2  10   2   5   2  60

r2 = geornd(0.01,[1 5])
r2 =
  65  18  334  291  63

r3 = geornd(0.5,1,6)
r3 =
   0   7   1   3   1   0
