This should get you started. This solution only saves the h and pValue outputs - you can add in the stat and cValue variables by following my example. They are all scalar values so it should be fairly straightforward to add those in (I intentionally left them out so you'd have some practice).
One note: you specified row names but I added them as column names (I assume that's what you meant since you only had 4 names and the adftest() requires a sample size of at least 10).
% Create fake data
array_x = rand(40,5);
h = zeros(size(array_x,2),1); %Column vector!
pValue = h;
for i = size(array_x,2)
[h(i),pValue(i)] = adftest(array_x(:,i));
end
ADFStat = table(h,pValue,'VariableNames',{'EUR_USD','GBP_USD'});
Please feel free to comment below with questions etc.
