calc_prec: Calculates Eigenvalues of the Preconditioner
In TMasak/surfcov: Random Surfaces' Covariance Estimation beyond Separability
calc_prec R Documentation
Calculates Eigenvalues of the Preconditioner
Description
Computes eigenvalues of the blocks of the circulant preconditioner, which is
denoted as c^{(1)} in Chan, R.H.F., & Jin, X.Q. (2007) An
introduction to iterative Toeplitz solvers.
Usage
calc_prec(M)
Arguments
M
the circulant symbol matrix generated by to_book_format()
Value
matrix of eigenvalues, one block of the preconditioner corresponds to
one column of the eigenvalue matrix
Examples
eigvals <- matrix(9:1,3)
M <- to_book_format(eigvals,3,3)
calc_prec(M)
