Hi, I have the following situation. In LMS algorithm I enter my input x as M by 1 matrix where M is number of taps and my weight vector is also M by 1.I initialize my w with all zeros. Now at time n e(n)= d(n)- w(n)'*x(n); w(n+1)=w(n)+mu*w(n)*e(n); I have to iterate this number of times.But since w and u are matrices.I am not able to use the 'for' loop to do the iteration.this is what is happening when I iterate these matreices error: to use A(I)=B I and B must have same lenths Need help on this. Thanks in advance, Mohan |

Hi, Do you want to store all the value of w i.e. in each iteration. If not instead of w(n) just use w in your equations. Otherwise you need to have a 2-D w matrix where one dimension is iteration index and other dimension is the weight values. e(n)= d(n)- w'*x; w=w + mu*w*e(n); Navan --- mohan prasad <> wrote: > Hi, > I have the following situation. > In LMS algorithm I enter my input x as M by 1 matrix > where M is number of taps and my weight vector is > also > M by 1.I initialize my w with all zeros. > Now at time n > e(n)= d(n)- w(n)'*x(n); > w(n+1)=w(n)+mu*w(n)*e(n); > I have to iterate this number of times.But since w > and > u are matrices.I am not able to use the 'for' loop > to > do the iteration.this is what is happening when I > iterate these matreices > error: to use A(I)=B I and B must have same lenths > Need help on this. > Thanks in advance, > Mohan > _____________________________________ > Note: If you do a simple "reply" with your email > client, only the author of this message will receive > your answer.
