Detailed Description

Discretized set of field profiles.

This class is a container for discretized field profiles, representing a solution for or correction to the bubble profile. Methods are provided to interrogate the dimensionality, size and discretization parameters of the profile set. It is also possible to evaluate a point in field space, either directly or via interpolation for off-grid points. Finally, it is possible to add one field profile to another. This is used to implement iterative corrections when calculating a profile solution.

It should be noted that the profile data is assumed to be spherically symmetric.

Examples:: general_fubini.cpp, and logarithmic.cpp.
