How to resample a timeseries to unique interval?. What I want is to resample the distance vector at regular time intervals (e.g. 1 ms, 2 ms, ..., n ms) What makes it difficult is that the maximum travel time, 994.6659, is less than the number of samples in the 2 vectors, therefore it is not straightforward to use interp1. Learn more about resample . The resampled signal starts at the same value as x but is sampled with a spacing of len(x) / num * (spacing of x).Because a Fourier method is used, the signal is assumed to be periodic.

Name of time-domain iddata object or a matrix of data. Consider using timetables instead of timeseries objects, where you can store time-stamped data as column-oriented data variables. Time series data¶ A major use case for xarray is multi-dimensional time-series data. In most cases, we rely on pandas for the core functionality. If you don't specify N, RESAMPLE uses % N = 10 by default. The length of the FIR filter RESAMPLE applies % is proportional to N; by increasing N you will get better accuracy at the % expense of a longer computation time. data.
