How to create variables as amany as the length of some vector c and assign data to them

The variables are a1 a2 a3.. a... a10

I would like to assign a1 = [ some data] but would like the script to input the index 1 after a

c = 1:10
for b = 1:length(c)
    v = 2*[1:b]
    eval(string(['a',num2str(b)])) = v
end
