For given Frequency Domain Operator S
computes ratio S^{-1}
at each frequency.
freqdom.inverse(S, n = NULL, Kconst = NULL, K = NULL)
first spectral density
number of observations used for estimation - the precision of inversion is calculated using this parameter
constant for heuristic (as in reg.dim.est
)
how many directions should be inverted (as in pseudoinverse
)
