growning data storage after each loop

Hey,

Hopefully someone can put me out of my misery;

I have 2 for loops which represent cycles. The first for loop has cycles 1 to n, with the for loop inside of that calculating data 1:100. I wanted to store the calculated data as a running total for the cycle which i have managed with this code:

    RT =0

 For Y = 1:5
        for x = 1:100
        value(x) = 2*x;

        if x >1 
            RT(x) =  (value(x)) + RT(x-1) 

        end 

    end
end

what i cant seem to do which i need to do is, after each cycle i want the running total to carry on, so the last value of the previous cycle becomes the starting value for the next cycle. The end goal being a whole running total stored of as many cycles as i input.

Could someone please help.

Thank you

Do you mean something like the code below? I'm assuming this is a small example and not your actual code, so I didn't bother optimizing this a lot.

RT =zeros(100,5);
for Y = 1:5
    for x = 1:100
        if x==1 && Y>1
            RT(x,Y)=RT(end,Y-1);
        end
        value = 2*x;
        if x ~=1
            RT(x,Y) = value + RT(x-1,Y);
        end
    end
end

@Rik Wisselink. Yess! Thank you very much that worked perfectly. This was just a representation of the code to save on space.

Thank you again for the help.
