Problem 649. Return the first and last characters of a character array
Return the first and last characters of a character array, concatenated together. If there is only one character in the character array, the function should give that character back twice since it is both the first and last character of the character array.
Example:
stringfirstandlast('boring example') = 'be'

There is a difference between string and char array since R2016b. Before that they could be used interchangeably, but now that is no longer true (although I believe some doc pages are still not careful about this).

The title and description have been updated, along with a few new test cases.
