findstr

Finds the starting positions of the shorter text inside the longer one (legacy).

Category: Language Fundamentals > Data Types

Syntax

k = findstr(s1, s2)

Description

findstr is kept for compatibility. Because it swaps its arguments silently, strfind(text, pattern) is clearer and is the recommended replacement.

Overlapping occurrences are all reported: searching 'ana' in 'banana' finds positions 2 and 4.

Input arguments

s1, s2

Character vectors. The order does not matter: the shorter is searched inside the longer.

Output arguments

k

Row vector of start positions, empty if there is no match.

Example

Overlapping matches

findstr('banana', 'ana')
findstr('abcabc', 'bc')

ans = 1×2

     2     4
ans = 1×2

     2     5
