How to assign data to dynamic variable

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

[KSSV]

c = 1:10 ; 
a = cell(length(c),1) ; 
for i = 1:length(c)
    a{i} = 2*[1:i] ;    
end
celldisp(a)

 
a{1} =
 
     2

 
 
a{2} =
 
     2     4

 
 
a{3} =
 
     2     4     6

 
 
a{4} =
 
     2     4     6     8

 
 
a{5} =
 
     2     4     6     8    10

 
 
a{6} =
 
     2     4     6     8    10    12

 
 
a{7} =
 
     2     4     6     8    10    12    14

 
 
a{8} =
 
     2     4     6     8    10    12    14    16

 
 
a{9} =
 
     2     4     6     8    10    12    14    16    18

 
 
a{10} =
 
     2     4     6     8    10    12    14    16    18    20

 

You can access cell a by a{1},a{2}, .....a{10}.

DEfining variables like a1, a2, ...a10 is meaning less and not required.
