Example: (%i1) load ("fft"); (%i2) array (aa, float, 3, 3)$ (%i3) array (bb, float, 3, 3)$ (%i4) fft (aa, bb)$ Maxima encountered a Lisp error: Typeerror in KERNEL::OBJECTNOTTYPEERRORHANDLER: #2A((0.0 0.0 0.0 0.0) (0.0 0.0 0.0 0.0) (0.0 0.0 0.0 0.0) (0.0 0.0 0.0 0.0)) is not of type SEQUENCE Looking at fft.lisp, I don't see that it's designed to handle 2dimensional arrays, although I could be overlooking something. Perhaps we can consider either getting FFT to handle 2dimensional arrays, or just cutting out the stuff about 2dimensional arrays in the documentation. I guess I'm in favor of the latter.

Maybe at some point in the future someone will make a feature request for 2d FFT. In the meantime, I'm closing this bug report.
