Detailed Description

APH(2) fit of three moments, with a fallback to adjusted moments (matlab/lib/m3a/m3a/aph2/aph2_fit.m).

Exact fitting is attempted first with aph2_fitall; if that yields nothing the moments are relaxed with aph2_adjust ('simple' method) and the fit is repeated. The first solution is returned, together with all of them.

Gated on transcendental arithmetic through aph2_fitall and aph2_adjust.
