Sinc Resample 1.0 Description
Description: 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:

The INTERPFT function does sinc interpolation by taking an FFT, padding its end with zeros, and then taking an IFFT. Essentially, INTERPFT resamples the signal after low-pass filtering it.
Instead of putting all zero padding at the FFT *ends*, that padding can be split so that some are at the beginning of the FFT and some are at the end. The result is identical to resampling the signal after bandpass filtering it.
Resamples X(n). Y(n) = X(alpha*n), where alpha is a resample interval. For example, if X is data sampled at 1000 samples per second and you would like to transform it to the equivalent of 1100 samples per second use alpha= 1000/1100 (.9091); for...
