i found a usage of fopen which is not found in MATLAB documentations
here is my code
s = 'name';
fileID = fopen([s,'.txt'],'w');
this syntax really works. but i could not found the source.
the ordinary usage of fopen could be
fileID = fopen('name.txt','w')
is MATLAB documentation uncomplete?
thank you!

"but i could not found the source."
Did you try reading the source that I gave in your earlier question?
"is MATLAB documentation uncomplete?"
No. Just because you combined several commands and could not find that specific combination of commands in the documentation does not mean that the documentation is "uncomplete". Lets try another example: here are some commands that I combined just now:
Will we find that combination in the MATLAB documentation? I very much doubt it. Does this mean that the MATLAB documentation is "uncomplete" ? No, it does not. It means the user needs to look up each of those commands separately, understand how they work, and undertand how the combination works. This is exactly the same for all programming languages.

It’s not so complicated [] is used for concatenation
['name', '.txt'] % try it in command window and see what happens

yes, thank you all.
as Walter Roberson says '...including a variable that holds the file name.'
that's everything that i need.
