Rename variable throughout project/directory

I have inherited a project (a director and a subdirectory of matlab files) where variable names are unhelpful. To make this clear to myself I want to rename some variables.
I know I can rename a variable throughtout a single file with shift enter or search. But it's tedious to do this for every file. Is there a way to rename/search and replace throughout a project?

"The variables names are often fields in structs"
Aaah, so structure fieldnames, not variables names. This important information is missing from your question.
"Maybe something wrong with this approach"
No, passing structure is a recommended way of passing lots of parameters between workspaces.
" Is there a way to rename/search and replace throughout a project?"
I recommend using Notepad++ features:
- search and replace in multiple files under some folder
- filters for filenames, extensions, etc.
- search pattern using literals or regular expressions.

Is this a joke? Every modern IDE can do that. This is called refactoring. Finally give more resources to Matlab's IDE department so they can write a worthy interface. Take a look at "Microsoft Code". Even Notepad++ can handle it! Just not Matlab.

Use grep sed command of linux system. There light be some linux shell (cygwin?) on windows that you can install if you are under Windows.

You can modify the field names using regexprep :
% Get a list of M-files:
List = dir(fullfile(Folder, '**', '.m'));
for k = 1:numel(List)
file = fullfile(List(k).folder, List(k).name);
str = fileread(file);
str = regexprep(str, 'Struct\.oldfield\s', '.newfield ');
writelines(str, file);
end
This does not consider sub-structs, or a directly following parenthesis or equal character. Hopefully a regexp hero can post a more powerful pattern.
But keep in mind, that the problem is not trivial. This modifies and comments strings also. After the conversion you should compare the new file with the original one and check all changes manually.
