NFFT on a Zoo?
I have an irregular time series in a Zoo object, and I've been unable to
find any way to do an FFT on it. More precisely, I'd like to do an NFFT
(non-equispaced / non-uniform time FFT) on the data.
The data is timestamped samples from a cheap self-logging
accelerometer. The data is weakly regular, with the following
characteristics:
- short gaps every ~20ms
- large gaps every ~200ms
