Function File: irsa_normalize.m

[xpn,fmaxn,xp1,nfac] = irsa_normalize( xp, [fmax] )

Normalize xp to [0, (N-1)/N], compute the last frequency point below or equal to the given bandlimiting frequency fmax and scale it according to the normalization.

Input:

xp : Vector – sampling points

fmax : Scalar – band limiting frequency of signal sampled at xp

Output:

xpn : Vector – normalized sampling points

fmaxn : Scalar – last discrete frequency corresponding to xpn

xp1 : Scalar – offset of xp ( xp(1) )

nfac : Scalar – normalization factor

Note:

You get xp from xpn by computing xp = xpn*nfac+ xp1. Due to discretization the actually used fmax for xp is fmaxn/nfac.
