im working on lms algorithm i want to use the lms function to update my filter coefficients instead of this :"w = w + mu * u * e(n)" any help please?
 

u can write a function yourself. follow this %%adsp question simulaation
clear all
close all
d=[1 -1 1 -1]';
noise=[-.1 0.1 0.2 0.1]';
h=2;
m=2;
w=[0 0]';
mu=0.339;
u=h.*d+noise;
for n=1:4,
if n==1,
u_use=[0 u(n)]';
elseif n==5,
u_use=[u(n-1) 0]';
else
u_use=[u(n-1) u(n)]';
end
d_hat(n)=w:),n)'*u_use;
err(n)=d(n)-d_hat(n);
w:),n+1)=w:),n)+mu*u_use*err(n)
end
u'.*w(2,n+1)
 
thank u but i want to use precisely the lms function to update my filter coefficients instead of this line "w:),n+1)=w:),n)+mu*u_use*err(n)"
 

then use functional block lms filter search matlab help
