Hi,

The solution I found in my code was to create a struct or class to hold the
interpolation object as well as the X and Y arrays. I can pass an object
created from this to my functions instead of the interpolation object alone.

Thus I can still update the arrays whenever I want and when the object goes
out of scope, everything is destroyed.

Toy out.
