AR Coefficients

Post by caranico » 20 Dec 2011, 11:59

Hi,
I want to see the ARCoefficients in matlab. I call the mem function (MEX file) from matlab and i build the amplitude spectrum but now i need to see the AR coefficients because i want to use them for a neural network.
Could someone help me?

There is no way to do this in Matlab using the BCI2000 mex functions; you can, however, get the coefficients while running BCI2000. The MEM algorithm uses the Burg method to find the coefficients, so you could use the

Code: Select all

method to get the coefficients in matlab. They will be nearly identical to the values obtained in BCI2000.
