Strings
regexp() is a MATLAB®-compatible strings function for match a regular expression against a string. default returns 1-based start indices of matches; pass 'match' for matched substrings, 'tokens' for capture-group arrays, or 'split' for the pieces between matches. Run it online in your browser with SimLab — free, no install, no license required.

What does regexp() do?
Match a regular expression against a string. Default returns 1-based start indices of matches; pass 'match' for matched substrings, 'tokens' for capture-group arrays, or 'split' for the pieces between matches. It is a MATLAB®-compatible strings function available in SimLab with the same calling syntax as MATLAB® — typically: regexp(str, pattern).
