Using load for different files with varying names

I have 25 files with .mat files, naming from data1 to data25

how to load them properly without manualy typing from 1 to 25

Here is my idea and the error

```

for i = 1:1:25

load('data%d.mat',i)

end

```

Error using load

Must be a text scalar.

How about the following?

for kk  = 1:25
    fileName = sprintf('data%d.mat', kk);
    load(fileName)
    %
    % Some process for each file
    %
end

@Miraboreasu: Note that LOADing directly into the workspace often leads to problems processing the loaded data, exactly as your follow-up question indicates:

It is strongly recommended to LOAD into an output variable:

S = load(..)

and then access the fields of S.

Yes, of course it is recommended to load into an output variable, as you mentioned.

Thank you for your additional comment !
