1) There is/was some discussions about special matrix types and how they

Can anybody comment on this? If I do this, should I implement it in a
more abstract way to allow for different "shapes"?

`That page is pretty much out-dated (last edit was in 2009). I can't
``recall any activity regarding Toeplitz matrices.
``If you want to implement this, perhaps start looking at how
``DiagonalMatrix is implemented (regarding our internal interface).
`

2) The FFT module is listed as unsupported; this would make any method
for solving linear systems based on FFT unsupported as well.
Is this
http://eigen.tuxfamily.org/index.php?title=EigenFFT
and this
http://eigen.tuxfamily.org/index.php?title=Status_of_unsupported_modules
up to date considering the status of the FFT module?

`I'm afraid that is still the current status (i.e. no significant changes
``since 2009). You should probably contact Mark (if he does not respond by
``himself), whether there has been any activity, though.
`

What would be needed to move at least the 1d FFT kissfft implementation
to 'supported'?

`I doubt that we'll move FFT to supported in 3.3. Also, if you provide a
``new module, it should first be implemented as unsupported, anyways.
