findstr

Find one string within another (returns positions of all occurrences).

Syntax

k = findstr(str1, str2)

Description

Searches for the shorter of str1 and str2 within the longer, returning a vector of starting indices for each occurrence. Returns an empty array if no match is found.

Note: MATLAB has deprecated findstr in favor of strfind, which has clearer asymmetric semantics. Prefer strfind for new code.

Example

findstr('the cat', 't')    % [1 5]
