Xscale
Xscale a library of multi-dimensional signal processing tools using parallel computing
Xscale is defined to work with multi-dimensional self-described arrays using the xarray objects. Xscale also benefits from parallel computation of several numpy and scipy functions implemented in the dask library. Most of the tools found in xscale are developed to analyse and separate time and spatial scales.
