Looping through different files with sprintf

Hi, I am trying to run some data analysis on data from an experiment and the different participant results are stored in separate MAT files. The data starts from sub01.mat -> sub13.mat. With teh code above, I get an error as it starts the file name at sub1.mat instead of sub01.mat. Any suggestions?

Read the documentation for sprintf.
filename=sprintf('sub%02d.mat',s);
You also probably want to actually the loaded data:
ind=S.outDat(:,i)==k;
% ^^

Hello
I see you get already an answer
otherwise you can also do the same loop using dir
example attached
my solution works even if the data are stored in a different variable name for each mat file
all the best

There are several problems with your code:
- Why use clear all? Even clear itself is not really needed if you don't make any typos. clear all should appear exactly once in your entire codebase.
- Why use close all? You aren't opening any figures or plotting anything, so why close all figures? Maybe there is a figure open with usefull data, or even a GUI.
- Why use eval? You can simply loop through the fieldnames: data=MyStruct.(fn{n});. No eval required.
