Description

Orientation-averaged spectrum

Usage

spectrum_oa(cluster, material, medium = 1.33, quadrature = c("gl", "qmc", "random", "cheap"), Nq = 100, iterative = FALSE, precision = 0.001, Qmax = 10000, dN = Nq, method = c("solve", "cg", "oos"), Nsca = 50, maxiter = 30, tol = 1e-04, progress = FALSE, verbose = TRUE)

Arguments

cluster
cluster (list)
material
material
medium
refractive index medium
quadrature
quadrature method, using either Gauss Legendre quadrature (default), Quasi Monte Carlo, random, or "cheap" (3 Axes)
Nq
number of integration points
iterative
logical, increase N until convergence (QMC only)
precision
relative diff between two runs (QMC only)
Qmax
maximum N if convergence not attained (QMC only)
dN
iterative increase in N (QMC only)
method
linear system (solve), conjugate-gradient (cg), or order-of-scattering (oos)
Nsca
quadrature points for scattering cross-section
maxiter
integer termination of iterative solver
tol
double, tolerance of iterative solver
progress
print progress lines
verbose
display messages
