This utility will replace all string matches in the target files with a given string. This is similar to 'Replace all' in the editor, except that it can be used programmatically and on multiple files.
For instance, to replace all occurrences of 'abs' with 'mag':

>> find_and_replace('my_file.m', 'abs', 'mag')

Both the "match" and "replace" inputs can be regular expressions. For instance, we can replace all calls to sqrt(...) with my_sqrt(...), keeping the function's argument by using regular expressions.

>> find_and_replace(file_names, 'sqrt\((.*?)\)', 'my_sqrt\($1\)');

For more examples:

>> help find_and_replace;

Some knowledge of regular expressions is helpful, but not required, to use this tool. See 'Regular Expressions' in MATLAB's documentation.
