Cell array as input for loop

So the input is a 1D Cell array. So im wishing to pass each element of the Cell Array into a function one by one. And that should give me 2 values. And then i need to put these into a 2D array, each row being the 2 values of one element. So i should have a 200x2 2D array. I used a for loop for that, but im not sure how to loop through the whole array of elements?

ExtractElement = Element{1};
ElementAverage = zeros(200,2);

for i = 1:length(Element)
    [A,B] = AverageElement('ExtractElement'); %This is the function
    ElementAverage(i,:) = [A,B];

end
end

Then im stuck

My problem here is i dont know how to loop the length of the array. Any help on that?

I don't understand why you're using cell arrays at all instead of normal numerical arrays. And Element is a 200 row by 1 column array of cells - okay fine. But why is ExtractElement equal to the contents of the first cell, and why are you passing the literal string 'ExtractElement' (which has absolutely nothing to do with the variable ExtractElement) into your function? Even if you were to pass the contents of the ith cell into AverageElement(), what ARE the contents of that cell, and why does averaging it produce two output values? Basically the question does not make sense.

I think you would benefit greatly by reading the FAQ on cell arrays to understand what they are and how they work: http://matlab.wikia.com/wiki/FAQ#What_is_a_cell_array.3F

"problem here is I don't know how to loop [over] the length of the array"

Hint:

    cac = {'a','b','c'};
    % loop over all columns
    for c = cac
        disp(c{:})
    end

displays

    a
    b
    c

&nbsp

"But i want to store the values each time. how would i do that?" displays

Hints:

    >> cssm
    ans = 
        'a'    [97]
        'b'    [98]
        'c'    [99]
where

    function out = cssm
        cac = {'a','b','c'};
        out = cell( length(cac), 2 );
        for jj = 1 : length( cac )
            [ out{jj,:} ] = one2two( cac(jj) ); 
        end
    end
    function    [ str, num ] = one2two( c )
       str = c{:};
       num = double( str );
    end

&nbsp

and

    >> cssm
    ans =
              97        9409
              98        9604
              99        9801

where

    function out = cssm
        cac = {'a','b','c'};
        out = zeros( length(cac), 2 );
        for jj = 1 : length( cac )
            out(jj,:) = one2two( cac(jj) ); 
        end
    end
    function    n = one2two( c )
       n = double( c{:} );
       n = cat( 1, n, n*n );
    end

Yup so i did that thanks! But now since the values inside the loop keeps changing. But i want to store the values each time. how would i do that?
