Deleting Files in other folders with different names

Hello to all!

My matlabcode .m is in an specific folder. In the Same Folder there are two Folders. These two folders have every Time I execute the Matlab code Different names. The only thing that remanes the same is the ending of the folders for example:

Sample1_data

Sample2_data

and the next time the folders names are

test1_data

test2_data

So my question is. How can i get my matlab code running like this:

Go in the first *_data folder and delete expample.png

go to second *_data folder and delete example.png

I hope you guys understand what i want. My english is not very good

Thanks to all!

This should get you started (untested):

S = dir('*_data');
N = {S([S.isdir]).name};
for k = 1:numel(N)
    F = fullfile(N{k},'example.png');
    delete(F)
end

The documentation describes looping over files, but the same applies to looping over folders:
