How do i get the output for each iteration of code?

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:

    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

but that will only give me the 'c' for the second iteration, how would i get it for both of them?

This is just a typo:

out{iter} = c;  % instead of out{k}

Oh, now it worked fine, thanks!

@Jan: thank you Jan, well spotted! Fixed now.

Just one question, if i want to save matrices with different sizes how would i do it? Because using the cell array it doesn't seem to work

[Stephen23]

"if i want to save matrices with different sizes how would i do it? Because using the cell array it doesn't seem to work"

Use a cell array. It makes no difference how large the arrays are that you put into the cells of a cell array. Here is a simple example:

>> C{1} = 1:2;        % two element vector
>> C{2} = randi(100); % ten thousand element matrix

No error for me. I see no reason why it would not be possible to use a cell array. You have a bug in your code, so you should show the code that you are using. If you are getting an error then please show us the complete error message. If you are getting unexpected results then please describe in detail what you expect, and what you get.

oh, i'm sorry, i actually described the problem completely wrong, the cell array works fine, it's because i tried to use cell2mat for the cell array that had two matrices with different sizes and the concatenation didn't work
