Why do we deal with perfect numbers?
I don't suppose they have any real use, but the Greeks gave them importance and were believers in numerology.
The matter can be generalized some to Amicable Numbers, such as 284 and 220, where each has divisors less than itself that sum up to the other.

The POLYWARP procedure performs polynomial spatial warping.
Using least squares estimation, POLYWARP determines the coefficients Kx ( i,j ) and Ky ( i,j ) of the polynomial functions:
Kx and Ky can be used as inputs P and Q to the built-in function POLY_2D.
