Hello everyone,

I was trying to understand the various parameters used in adaptfilt.lms() function

The general form is:

H = adaptfilt.lms(L,STEPSIZE,LEAKAGE,COEFFS,STATES)

Here, L : lemgth of the adaptive filter

STEPSIZE : μ

LEAKAGE : α

COEFFS :

, i.e., Initial coefficient vector of the adaptive filter

where,

But, i was not able to figure out what is STATES ?

In Matlab, it is given that STATES is a vector of initial filter states. It must be a length L-1 vector.

STATES defaults to a length L-1 vector of all zeros.

But I don't understand how it is related to LMS Algorithm described by the above equations

so, please anyone explain it
