Trying to cycle through my variables with a for loop.

for i=1:20
Data = sprintf('Data%i',i);
DataNew(:,i) = mean(Data);
end
I have 20 Data arrays labeled Data1-Data20 and want to cycle through them in a for loop and do some calcs like mean, or run them all through a formula. But I keep getting errors that the Data is a char, how do I do this correctly?

I would do it in two steps, first to create a cell array from the individual arrays (so you don’t have to go through that step ever again), and second, calculate the means:
Data1 = randi(10, 5, 1); % Create Data
Data2 = randi(10, 7, 1);
N = 2;
for k1 = 1:N
Data{k1} = eval(sprintf('Data%d',k1)); % Create Cell Array From Individual Arrays
end
for k1 = 1:size(Data,2)
DataNew(k1) = mean(Data{k1});
end
