MATLAB: How do i get the output for each iteration of code

Question

I have a program in which i run two matrices through the same code and they give me an output for each iteration(the iteration is associated with which matrix i run through it). The thing is, in this code i run through seven iterations again(this iteration has the purpose of closing in the result i want), how do i get the last output for each matrix iteration? I mean i could remove the semicolon and check manually, but is there an easier way to do it? simply put the code looks like this

    for iter=1:2
        x=y{iter};
        c=[0;0;0;0];
        ...
        for k=1:7
            ...
            c=a+b;
        end
    end

in which x are the different matrices i use in the code, y is the variable i use to call upon the different matrices and this c is what i'm looking for. Or even save those c's on a variable and/or a file, that would be perfect

edit. I got how to show them by using this

if k==7
  disp(c)
end

but i don't know how to attach it to a variable, or cell array etc

By using indexing. Indexing is a basic concept that is shown in the introductory tutorials:

https://www.mathworks.com/help/matlab/getting-started-with-matlab.html

    out = cell(1,2); % preallocate an output matrix.
    for iter = 1:2
        x = y{iter};
        c = [0;0;0;0];
        ...
        for k = 1:7
            ...
            c = a+b;
        end
        out{iter} = c; % this will get the last value of c
    end
