Problem 2061. Narcissistic number ?
Inspired by Problem 2056 created by Ted.
In recreational number theory, a narcissistic number is a number that is the sum of its own digits each raised to the power of the number of digits (Wikipedia).
For example :
153 = 1^3+5^3+3^3 = 1 + 125 + 27 = 153
1634 = 1^4+6^4+3^4+4^4 = 1 + 1296 + 81 + 256 = 1634 are narcissistic numbers.
Simply return 1 (true) if a supplied number is narcissistic or 0 (false) if not.
The tips num2str(666)-'0' = [6 6 6] should be useful.
