FFT

Always forget this:

Indices	DC	POSITIVE	NYQUIST	NEGATIVE
C	`0`	`1 .. N/2-1`	`N/2`	`N-1 .. N/2+1`
Matlab	`1`	`2 .. N/2`	`N/2+1`	`N .. N/2+2`

^ Indices^DC^ POSITIVE ^ NYQUIST ^ NEGATIVE ^
^ C  | ''0'' | ''1 .. N/2-1'' | ''N/2'' | ''N-1 .. N/2+1'' |
^ Matlab | ''1'' | ''2 .. N/2'' | ''N/2+1'' | ''N .. N/2+2'' |

Example of problem

So look

I can edit this subsection

Without a problem

And this one

Is okay too

But how do I edit here

Without editing the whole page. Before I could edit this? What has changed?
