Try this:
N = size(a,2);
powerVector = 10.^[N-1:-1:0]';
requiredVector = a*powerVector;
Hope this helps!

The other answer will only work for a very limited set of problems, and will break with even the slightest change, like having a number bigger than 10 as an element in the array. You can still use it if it works for you, but a much more robust way is below:
a = mat2str(a);
a = strrep(a,' ','');
a = str2num(a);

It is indeed 1x3 for me. You are leaving out something.
