Hi All,
I am seeking to be able to find a phrase, say 'XXXX' among a master script that calls some 1000 other functions. The functions are all in a directory with many subfolders as well.
I am hoping there is a way to do this withuot having to open each of the functions individually and then doing a search.
Much thanks,
Rand.

You can use dir(): https://www.mathworks.com/help/matlab/ref/dir.html to get a list of all files. Use a loop to iterate over them and use strfind(): https://www.mathworks.com/help/matlab/ref/strfind.html or regexp(): https://www.mathworks.com/help/matlab/ref/regexp.html to search the string in the file.
R2020b also introduces pattern(): https://www.mathworks.com/help/matlab/ref/pattern.html.

You can use Matlab tools, as Ameer describes, but you can also use external software. I personally find the performance of searches like this excellent when I use Notepad++. You can use normal searches and regular expression. You can also filter the file type and search a single folder or include all subdirectories.

You can use the Find Files tool in the File section of the Home tab of the toolstrip.
