pysteps.postprocessing.probmatching.nonparam_match_empirical_cdf(R, R_trg)

Matches the empirical CDF of the initial array with the empirical CDF of a target array. Initial ranks are conserved, but empirical distribution matches the target one. Zero-pixels (i.e. pixels having the minimum value) in the initial array are conserved.

Parameters:

R : array_like

The initial array whose CDF is to be matched with the target.

R_trg : array_like

The target array.

Returns:

out : array_like

The matched array.
