I computed the divergence of the horizontal wind filed using uv2dv_cfd and
uv2dvF_Wrap and get different answers. I don't understand why the answers
are different. I would like to know what both functions do and why the
results differ. Could you please help me?

I am also inverting the lapacian by using the function ilapsF_Wrap. Could
you please tell me what the function does? Which equation is is solving? Is
the function doing more than the pure spherepack routine (it seems to be
like it)?

I am looking forward to hearing from you.

Kind regards,
