Solution to "MatFile objects must be scalar. Try assigning the object to a scalar variable."?

I have quite a few .mat files that I used to load them. But it uses too much memory. I tried to use matfile instead of load but I couldn't.

for i = 1:numel(files)
    I2(i) = matfile(['saved_images/2/read/', files(i).name]);
end

It gives me this error:

MatFile objects must be scalar. Try assigning the object to a scalar variable.

I have to use them as an array. I can't use a MatFile variable for each .mat file. What is the best way to solve this problem?

      I2{i} = matfile(['saved_images/2/read/', files(i).name]);
