cda 1.5.1
INTERNAL CHANGES
* use symmetry to calculate only half of the off-diagonal interaction matrix blocks
* tweak LinkingTo Rcpp for CRAN
cda 1.5
INTERNAL CHANGES
* complete rewrite of the internal functions to clean up and optimise the passing of parameters
* cross-sections are now calculated for multiple incident angles at once
* corrected a missing factor of 1/sqrt2 in dispersion calculation with circular polarisation
* Rcpp::function tweaks to please c++11 and clang for CRAN release
* more complete internal tests based on testthat (see inst/tests)
* (non-exported) standalone R version of the core CDA functions for testing and debugging
USER VISIBLE CHANGES:
* dispersion_spectrum now calculates extinction, absorption and scattering
* the linear system is now always solved with a (multiple) right-hand side (incident fields), the option to invert the matrix has been removed. It was slower in most cases anyway
* linear_extinction_spectrum no longer exists. Use the more versatile dispersion_spectrum instead
* demos updated to reflect the internal changes
cda 1.4
USER VISIBLE CHANGES:
* QMC angular averaging gains an 'iterative' routine, adding new integration points until specified accuracy is reached
* a 'cheap' (fast) version of angular averaging is added, only using 3 angles but providing in most cases a good estimate of full averaging
BUG FIX:
* Armadillo 0.190 brought some changes that made the results incorrect at the C++ level. First, the diagonal part of the interaction matrix was filling the off-diagonal blocks with non-zero elements due to non-initialisation of the matrix. Second, the integer flag for the Axes (x, y, z) was passed as a arma::uvec, where arma::ivec should be used.
cda 1.3.3
* CRAN update
* submitting more complete copyright information at the request of CRAN maintainers, to explicitly state the copyright of LAPACK routine src/zgels.f
cda 1.3.1
INTERNAL CHANGES:
* depends on dielectric 0.2.2
cda 1.3 (2012-11-28)
INTERNAL CHANGES:
* fixed polarisation and orientation issues in dispersion calculations
* cleaned up internal code
* started using testthat for consistency checks in future releases
USER VISIBLE CHANGES:
* function names have changed to be more consistent
* all dimensions are now in nanometres
* updated the licence to GPL3 + LICENCE file
DOCUMENTATION:
* new examples under inst/wiki formatted for knitr+markdown and updating the github wiki
* cleaning up demos, examples and vignettes
* link to github + wiki as the source of documentation
cda 1.2 (2012-08-08)
INTERNAL CHANGES:
* explicit export of functions
* theme_minimal adapted for ggplot2
NEW FUNCTIONALITY:
* dispersion_spectrum() calculates the optical response as a function of incident angles and wavelength, for two orthogonal linear polarisation states
cda 1.1.3 (2012-02-07)
* fixed bugs for ggplot2-0.9.0
cda 1.1.2 (2011-10-07)
* fixed implicit conversion of sqrt(2) to sqrt(2.0) for Solaris
* fixed .onLoad function
cda 1.1.1 (2011-09-04) (ftp error)
cda 1.1 (2011-09-04)
----------------------------------------
USER-VISIBLE CHANGES:
* New dependency on randtoolbox (Halton sequences for Quasi-Monte Carlo angular averaging.
ENHANCEMENTS:
* Choice of three methods for angular averaging: regular grid, Gauss Legendre Quadrature, Quasi-Monte Carlo (default). N now refers to the number of integration points (GL may use a slightly higher number of points, rounded as ceiling[sqrt(N)]).
* added tests/ subdirectory, featuring numerical tests of consistency.
BUG FIXES:
* Removed Encoding: UTF-8 from Description
cda 1.0 (2011-05-15)
----------------------------------------
Initial CRAN release.
