How to generate automatically multiple symbolic values??

i want to generate for 30 values. because i have to store it to array.

 a(1) =  [a1 a2 a3 a4 a5 a6 a7 a8 a9 a10 a11 a12 a13 a14 a15 a16 a17 a18 a19 a20];

strictly i need a1 a2 a3...i don't need a(1), a(2).... i want it to generate randomly. if i enter length = 5 then generate only

 [a1, a2 ,a3,a4,a5]

a = sym('a', [1 30])

I am not sure what your mention of randomness is? If you want to scramble the order of these then you could use

a = a(randperm(numel(a)));

Don't do that.

@Ranjan Kumar Singh: Really, don't do that:
