Sure. Make those few lines of code into a function and then call the function on each cell using cellfun().
(I modified the code to keep the values in the first column the same as what they were in the original matrix, rather than setting them all to 2, since they vary in the matrices in this cell array.)
load('matlab.mat');
new_Data = cellfun(@fill_to_100,Data,'UniformOutput',false);
disp(Data{1});
disp(new_Data{1});
disp(Data{end});
disp(new_Data{end});
function new_A = fill_to_100(A)
new_A = zeros(100,3);
new_A(:,1) = A(1,1);
new_A(:,3) = 1:100;
[ism,idx] = ismember(1:100,A(:,3));
new_A(ism,2) = A(idx(ism),2);
end
