expfit vs harminv - which is faster/smaller ?

[Sergei Steshenko]

Hello All,

there is 'expfit' in the forge package and there is 'harminv' which is a
standalone program (and a library if one needs).

If I understand correctly, they both do the same thing.

It looks like both are based on BLAS, but maybe somebody has experience with
both and knows which of them is faster and which of them has smaller memory
footprint.

I think they are about equal, but just want to make sure.

Thanks,
  Sergei.
