When you write

a1 = 1;
a2 = 2;

You are creating two new variables with values 1 and 2.

What about:

vals = {'1','2'};
newa = strrep(a,a,vals);
disp(newa)

Answer 2

The following might give some insight

a1 = 1 ; a2 = 2 ; A = {a1 a2} ; % declaration
disp(A)
A{1} = 10 ; % change the contents (hidden by the semi-colon)
disp(A)
a1 = 3      % does not change the contents of A
disp(A)

You've lost me … Do you understand the concepts of variables, strings, doubles and cells? If not, take a look at the documentation.
