Track components (bands) of a order spectrum.

Usage
otrack1(a, df, f1, o, ob, oini})
a
amplitude or power spectrum (vector)
df
frequency resolution of a in Hz; 0 < df
f1
frequency of the 1st order in Hz; 0 < f1
o
tracking orders (scalar or vector); all orders must be greater than 0
ob
width of order bands; 0 < ob
oini
amplitude for unassigned order lines
Description 1
The function computes the maximum spectrum amplitude oa[i] for each order band i:
f1*(o[i]-ob/2) .. f1*(o[i]+ob/2); with: i = 0..nrow(o)-1
Result
The amplitudes oa[i]. The result has the same type as o.
