Adopted from Data assimilation for spatio-temporal processes - p250 - Sebastian Reich
Usage
simple.local(Pf, distance.mat, scalef = 2)
Arguments
- Pf
Forecast error covariance matrix
- distance.mat
is matrix of distances between sites.
- scalef
scalef is a numeric value that requires tuning and it controls the shape of the corrolation function
Value
It returns a localized covariance matrix by taking a Schur product between Pf and a corrolation function
