I vaguely remember that one has to use a larger matrix that
somehow makes the problem look like the one for circulants.
No more than that, sorry.
And that recollection was almost certainly wrong.

Within a few hours I can only see that there are FT methods
for circulants, and that the weighted FT does the same
for f-ciculants, as defined on p.132 of

  Dario Bini, Victor Y.\ Pan:
  {Polynomial and matrix computations, vol.1: Fundamental algorithms},
  Birkh\"{a}user, (1994).

Richard Brent could surely tell what the state of knowledge is.

Best,  jj
