Earth spherical harmonics about sphericalharmonicexpansions.jl

Not out of the box. Currently, our package contains methods to work with expansions of solid harmonics (r^nYlm, n>=0).

As I understand it you would need to work with n<=0. This possibility is not implemented. However, our package provides methods to analytically generate the Ylm as a starting point. There is a small documentation available, which can be found here.

No, I need to calculate the derivative of this. Is it posible?

[hofmannmartin]

I doubt it, since your expression is no polynomial.
