strfind

Find one string within another.

Syntax

k = strfind(str, pattern)

Description

Returns a vector of starting indices of every occurrence of pattern in str. Returns empty if no match. Asymmetric: pattern is searched within str (unlike findstr which searches the shorter within the longer).

Examples

strfind('hello world hello', 'hello')   % [1 13]
strfind('abcdef', 'xyz')                % []
