This is the code:

%% Applying the adaptive filter

% The adaptive noise canceller can use almost any adaptive procedure to perform its task.

% For simplicity, we shall use the least-mean-square (LMS) adaptive filter with 15

% coefficients and a step size of 0.00007. With these settings, the adaptive noise canceller

% converges reasonably well after a few seconds of adaptation--certainly a reasonable

% period to wait given this particular diagnostic application.

h = dsp.LMSFilter(15, 0.0007);

[y,e] = filter(h,x,d);

% [y,e] = FECG_detector(x,d);

plot(t,d,'c',t,e,'r');

%axis([0 7.0 -4 4]);
