Mean Comebacks
This could be very useful model when used in signal processing. I have implemented this to filter the disturbances in my ADC signals in my programming and it works good.

we had generated a signal and the we generated a random noise and add it to the signal,,then my using the lms algorithm we tried to cancel the effect of the noise on the signal and have the original signal back pure as possible

For vectors, Y = RUNMEAN(X,M) computes a running mean (also known as moving average) on the elements of the vector X. It uses a window of 2*M+1 datapoints. M an positive integer defining (half) the size of the window. In pseudo code: Y(i) = sum(X(j)) / (2*M+1), for j = (i-M):(i+M), and...

Given mean anomaly and eccentricity of an orbit, eccentric anomaly can be calculated using Kepler's Equation. However, the equation is nonlinear, and an iterative technique must be used. This program uses a fixed-point iterative technique to output eccentric anomaly to a user defined tolerance,...
