Under "Definition", the notation 

X=fft(x) and x=ifft(X)

is used.

Then under "Description", Y=fft(X) is used!  If you skip
that very first line in "Description" and read the rest of
the description using the definition in "Definition",
nothing makes sense!! It is talking about "X is padded with
zeros" which seems like the TRANSFORM is padded (according
to X=fft(x)) when really the INPUT is padded (Y=fft(X)).

I think this notation should be standardized for the next
release!

Just my $.02.
