Hello,
I would like to plot the time series of the coefficients from an adaptive filter object, in order to watch the convergence of my filter coefficients. How can I do this?
For example, using the example provided at the bottom of http://www.mathworks.com/help/dsp/ref/adaptfilt.html
How do I plot the time series of filter coefficients for each step, rather than just the final values?
Thanks

So I have to use simulink to do this, I cannot do it in code? I can generate the learning curves based off the filter error returned, but I cannot determine how to plot the time series of the coefficients.

Coefficients are vectors at every time step. Do you mean you want to have a 3-D plot that shows progressive change of the values of that vector across time?
