I want to write this make this script to function

name = regexp(sprintf('test%.3d.tif*',0:10 ), '*', 'split');

I got the result "test000, test001, test002, ..., test010" so I worked Then I want to make it to function so I did

function filename(basename, digits, start_no)
name = regexp(sprintf('basename %.digits d.tif*', start_no:10-start_no-1), '*', 'split');

end but it didn't work so I use %s

function filename(basename, digits, start_no)
name = regexp(sprintf('%s %. %s d.tif*', start_no:10-start_no-1, basename, digits), '*', 'split');

It still didn't work so how can I fix it. Thank you in advance

Please learn to format your posts, and be more descriptive. What does "it doesn't work" mean? Did MATLAB crash? Did you get an error message (what did it say?)? Did the computer catch fire? Be specific!

It would be less error-prone to use '\*' in the pattern instead of '*'.

There are several problems. For one, you don't specify any return argument for your function. Try this one:

function name = filename(basename, digits, start_no)
S = sprintf('%i',digits);
S = sprintf([basename, '%.',S,'d.tif*'], start_no:10-start_no-1);
name = regexp(S(1:end-1), '*', 'split');
