Hi,
I want know if there is a function could return the same results from 'Spectrum0.ar()' (a R fucntion)?
The description of 'Spectrum0.ar' :https://www.rdocumentation.org/packages/coda/versions/0.19-4/topics/spectrum0.ar
I am not familiar with signal processing, it will be great that there is a matlab function can return the same result.
A big thank you in advance!
Han

Hi Walter,
Thank you for your reply. I tried on pyulear but the result is quite different
y = [1,2,4,5,7,8,9]
pyulear(y) at zero is around 17
spectrum0.ar(y) is 43.69
