regexp

Match a regular expression against a string.

Syntax

k = regexp(str, expr)

Description

Searches str for matches of the regular expression expr and returns a vector of starting indices for each match.

MathJet’s regexp currently supports only the 2-argument basic form — the multi-output / option-flag forms ('match', 'tokens', 'split', 'once', etc.) accepted by MATLAB are not yet implemented.

Example

regexp('foo123bar456', '\d+')   % [4 10]   indices of digit-runs
