Compute an inverse of a given Frequency Domain Operator

Share:

Description

For given Frequency Domain Operator S computes ratio S^{-1} at each frequency.

Usage

1
freqdom.inverse(S, n = NULL, Kconst = NULL, K = NULL)

Arguments

S

first spectral density

n

number of observations used for estimation - the precision of inversion is calculated using this parameter

Kconst

constant for heuristic (as in reg.dim.est)

K

how many directions should be inverted (as in pseudoinverse)

Value

Frequency Domain Operator object
