So I have some files that I want to read all with 'sprintf'. If those files are named test1.txt, test2.txt, test3.txt... then I have no problem using
for k=1:n
sprintf('c:/folder/test%d.txt',k)

But if my files are name like text_0001.txt, text_0002.txt, and so on, I have not figured out away to use sprintf function to read those files.
Any suggestions?

this does not solve the problem. How can you make it skip the "_" and all the zeroes.
If the text file goes up to like text_0012.txt, ...text_0112.txt,...

Sorry, make that
sprintf('C:/folder/test_%04d.txt',k)

And if that isn't a sufficient answer to your question, then I would
question how it is that you expect a function that formats strings for
output to be able to *read* files.

Have you considered dir('C:/folder/test_*.txt') ?
