hilb

hilb — Hilbert transform

Calling sequence

[xh]=hilb(n[,wtype][,par])

`n`	: odd integer : number of points in filter
`wtype`	: string : window type `('re','tr','hn','hm','kr','ch')` (default `='re'`)
`par`	: window parameter for `wtype='kr' or 'ch'` default `par=[0 0]` see the function window for more help
`xh`	: Hilbert transform

returns the first n points of the Hilbert transform centred around the origin.

That is, xh=(2/(n*pi))*(sin(n*pi/2))^2.
