containstr

Search strings that match multiple patterns with a single line of code.

`containstr` returns TRUE if PATTERNs is found in text S.

`startswith` returns TRUE if any element of PATTERNs at the start of text S.

`endswith` returns TRUE if any element of PATTERNs at the end of text S.

Usage:

containstr(S, PATTERN)

startswith(S, PATTERN)

endswith(S, PATTERN)

--------------------------------------------------------------------------

Sometimes, I need to search strings that match multiple patterns.

The use of `strfind` (`regexp`) combing with for-loop (`cellfun`) makes the script look long and messy.

In newer version (R2016b), it is easy to do in a single line of code.

Just call the built-in functions `contains`, `startsWith`, or `endsWith`.

So, I created these functions for users with older version to search pattern in text.

These functions follow the same behaviour as Matlab's built-in.

Besides, my functions can treat search pattern as regular expression as needed.

No more for-loop is needed
