reverse operation to 'strsplit'

Hi! I have a cell like 'temp'. And I need to transform it (by adding '_') to get a char like 'a'. How can this be generated?

a = 'test_4_AA_5.txt';
temp = strsplit(a,'_');

You have been using this forum since 2020... now would be a good time to learn to use the MATLAB documentation: scroll to the bottom of the STRSPLIT documentation to find links to articles and related functions (e.g. STRJOIN).

Looking at the documentation of the function you are already using is easy and a good place to start solving your own questions.
