For my project, I'm designing an adaptive filtering for a ECG signal that is corrupted by movement artefacts.
I'm using the build-in Matlab function 'adaptfilt.lms'. Everything works fine, but I need the evolution of the filter coefficients of the adaptive filter. The function 'coefficients' only returns the latest set of coefficients, so that function has no use for me. I tried to edit the original code of the adaptfilt.lms but it seems like it is protected.
My question is: Is there a function that shows the evolution of the filter coefficients of the adaptive filter? Or how can I modify the existing code?
