generate a vector with a condition of a vector

I have a vector a

a = 1:1:20; 

and each increment of a by 1 and a <= 10 creates a vector b with condition:

a = 1 => b = 1:1:10; 
a = 2 => b = 2:1:10; 
a = 3 => b = 3:1:10;
...
a = 10 => b = 10:1:10; 

How to write a code to generate vector b ?

I have tried this, but it does not work.

if a<=1 && a<=10 
    b= a:1:10; 
end

Hard to understand your question. You can generate a vector b anytime you want. If you want a cell array of all vector b's.

for k=1:10;
  b{k}=k:10;
end
