The following implementation recursively resamples (duplicates) a matrix or a list (any iterable container type) containing numbers (any non-iterable objects). for finding maxima and minima respectively. Asking for help, clarification, or responding to other answers. from the comments. The object must have a datetime-like index ( DatetimeIndex, PeriodIndex , or TimedeltaIndex ), or the caller must pass the label of a datetime-like series/index to the on / level keyword parameter. [ ___] = resample ( ___ ,'Dimension',dim) Description example y = resample (x,p,q) resamples the input sequence, x, at p / q times the original sample rate. The resampled signal starts at the same value as x but is sampled with a spacing of len (x) / num * (spacing of x). np.convolve. In this article, we will be Resampling a NumPy array representing an image. As of SciPy version 1.1, you can also use find_peaks. I don't think there is a dedicated function for this. The resampled signal starts at the same value as xbut is sampled with a spacing of len(x) / num * (spacing of x). Usage: Interesting reading / comparison of many resampling solutions: 505). to If the new array is larger than the original array, then the new array is filled with repeated copies of a.
