random number within a rwo vector

I have a row vector say

>> A

A =[ -29  -17  -11  -10 -8 -8  -7  -2 -1  3 3  3  8 13  14]

I want to randomly generate a number within this A only.

How to do this?

[James Tursa]

A(ceil(rand*numel(A)))

[Raviteja]

A(fix(1 + (length(A))*rand(1)))

also working

[Andrei Bobrov]

A1 = unique(A)

out = A1(randi(numel(A1)))
