Answer 1

n = 2;

C = zeros(2*n,1);

for i=1:n
    a=input('a=');
    b=input('b=');
    C([2*i-1 2*i]) = [a; b];
end

C

It works, thank you.

Answer 2

One way:

n = 3;
C = zeros(1,2*n);
for i=1:n
ai=inputdlg('a=');
a(i) = str2double(ai);
bi=inputdlg('b=');
b(i) = str2double(bi);
end
C = reshape([a; b], 1, [])';

I prefer inputdlg to input.

It works too, thank you.
