y = RankOrderFilter(x, window, thd) runs a rank-order filtering of order N on x. y is the same size as x. If x is a matrix, RankOrderFilter operates along the columns of x.Rank-order filter calculates the p'th percentile of the data on an N sized window round each point of x. p can be a number...

As an example, suppose you had taken 155 seconds of data of the location (x,y,z) of a particle as a function of time (t). It is convenient to put that all into a struct, such as this one:>> datadata = t: [155000x1 double] x: [155000x1 double] y: [155000x1 double] z: [155000x1 double]If you wanted...

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...

This a very simple function that produces a condensed, approximate version of the time-series signal y, with each group of n adjacent points in y replaced by its average. You can use this to condense over-sampled signals so that subsequent processing will be easier and faster. Or you can use it...

function y = getiq(x,freq)this takes in the frequencies X that were received at a rate of FREQ and gives you a complex value which is I and Q - this is used when you have frequency X changing and the phase is cumulative - meaning it does not start each new frequency at the same spotORfunction y =...

Suppose that you have a signal Y (Y can be a time series, a parametric surface or a volumetric data series) corrupted by a Gaussian noise with unknown variance. It is often of interest to know more about this variance. EVAR(Y) thus returns an estimated variance of the additive noise.EVAR provides...
