Creating a vector with nested for loops and a while loop

Hello everyone!

I am attempting to an 8 element long vector that looks like this:

vector = [2 4 8 16 32 64 128 256]

To do this, I am nesting a while loop inside of two for loops like this:

 close all;
 clearvars;

 vector = zeros(1,2*2*2);
 c = 0;
 d = 1; 

 for a = 1:2
    for b = 1:2
        while c < 2
            d = d*2;
            vector(?) = d;
            c = c+1;
        end
    end
 end

Does anyone know what I can put in the place of the question mark so that every time we run through the loops, it adds the next value of d as the next element in the vector? Or are there more lines of code that I need to add to make this happen? Right now the code just keeps overwriting the first two elements of the vector and I don't know how to make it jump to the next elements.

Thank you in advanced, and have a great day!

Sincerely, Colin

P.S. Oh, I know that this is an extremely convoluted way of accomplishing this task; this bit of code is just meant to represent a much larger program I've written that doesn't fit into this web page.

One way

>> cssm
ans =
     2     4     8    16    32    64   128   256
>>

where

function vector = cssm
    vector = zeros(1,2*2*2);
    c = 0;
    d = 1;
    ix = 0;
    for a = 1:2
        for b = 1:2
            c = 1;
            while c <= 2
                d = d*2;
                ix = ix+1;
                vector(ix) = d;
                c = c+1;
            end
        end
    end
end
