findstr (MATLAB Functions)

Find string within another, longer string

Syntax

```
k = findstr(str1, str2)
```

Description

k = findstr(str1, str2) searches the longer of the two input strings for any occurrences of the shorter string, returning the starting index of each such occurrence in the double array k. If no occurrences are found, then findstr returns the empty array, [].

The search performed by findstr is case sensitive. Any leading and trailing blanks in either input string are explicitly included in the comparison.

Unlike the strfind function, the order of the input arguments to findstr is not important. This can be useful if you are not certain which of the two input strings is the longer one.

Examples

s = 'Find the starting indices of the shorter string.';

findstr(s, 'the')
ans =
     6    30

findstr('the', s)
ans =
     6    30
