ScaleTime - fast linear matrix interpolationI have recorded timeseries of e.g. size [100'000 x 10] and cut out chunks of about 100 frames according to some events and normalize them to exactly 100 frames.For this task, the direct approach with Matlab's INTERP1 works, but it is slow:...

When drawing financial time series from various markets, one usually needs to make some adjustments before evaluating the series. One of the major concerns is that due to different national holidays or working days across countries, the dates happen to be not synchronized. Clearly this could make...

In geomatic projects, it is often required to generate a regular grid containing points at pre determined intervals. Such grids could be used as a reference to georectify toposheets.This script when run asks for the bounding box of the study area in latitude and longitude, the sampling density or...
