Hi all. I have data matrix y(80x200). I'm trying to find AR Spectrum Estimation using Covariance method (pcov) for orders 10,50,100. But It gives an error at order 100. What should I do to fix it? (like zero-padding, maybe?) Or am I not able to use order 100?
Code:
x=y; %y(80x200)
order=100;
nfft=80;
pxx = pcov(x,order,nfft);
imagesc(pxx);
