If the input is a bandlimited signal containing components at DC - 0.5Fs where Fs is the sample rate, SINCRESAMPLE will return the signal that would have been seen with a higher sampling rate (and the same filter settings). The algorithm depends on the fact that the bandlimited signal is completely defined when sampling at Fs.SINCRESAMPLE returns the data convolved with a set of time-shifted windowed sinc functions, one for each of the samples [1..size(x,1)] in the input signal. End-effects are reduced by adding a reflected and mirrored copy of the data at the beginning and end of each column before resampling.Note that points at the end of Y (and/or beginning if SHIFT is negative) will be extrapolated beyond the boundaries of X. SINCRESAMPLE is a generalization of the method discussed in:T.Blanche & N.V.Swindale (2006)Nyquist interpolation improves neuron yield in multiunit recordingsJournal of Neuroscience Methods 155, 81-91http://dx.doi.org/doi:10.1016/j.jneumeth.2005.12.031
