For LanczosFilter Publisher's description


LanczosFilter is a Scripts software developed by Carlos Adrian Vargas Aguilera. After our trial and test, the software is proved to be official, secure and free. Here is the official description for LanczosFilter:

EditByBrothersoft: Apply the Lanczos filter to a real time series, in the Frequency space, i.e., using FFT which is faster than applied as a cosine filter in the time space.

Y = lanczosfilter(X,dT,cf,M,'low')
X - Time series
dT - Sampling interval (Default 1)
Cf - Cut-off frequency (default half Nyquist)
M - Number of coefficients (default 100)
and 'low' or 'high' depending if you want to get the Smooth or the noisy part of your data, respectively (default 'low', so it smooths).

NaN's elements are replaced by mean(X). If you have a better idea, just let me know.

It comes with an example, also take a look at the screenshot, where the filter is applied to each row.
