By building a Nonlinear function relationship between an d the error signal，this paper presents a no—
vel variable step size LMS(Least Mean Square)adaptive filtering algorithm．
LiScNLS is a Matlab application for the numerical study of some Nonlinear
differential equations of the form Lu=Nu, using the Lyapunov-Schmidt method.
Downloading the LiScNLS package creates a new LiScNLS folder on the computer.
