`find()`

as well as corresponding functions to find elements which
are either finite or non-finite, based on a suggestion we made. This may
need an RcppArmadillo specific
extension as R extends the IEEE logic to supported `NA`

,
`NaN`

and `Inf`

on floating point variables whereas
standard C++ (and hence Armadillo)
only supports the latter two. We hope to work on this `unsigned int`

vectors
and matrices are converted correctly, and I updated the short configure
script checking for complete LAPACK support to account for the R 3.0.3 or
later case.
Courtesy of CRANberries, there is also a diffstat report for the most recent release As always, more detailed information is on the RcppArmadillo page. Questions, comments etc should go to the rcpp-devel mailing list off the R-Forge page.## Changes in RcppArmadillo version 0.4.300.0 (2014-05-04)

Upgraded to Armadillo release Version 4.300 (Medieval Cornea Scraper)

faster

`find()`

added

`find_finite()`

and`find_nonfinite()`

for finding indices of finite and non-finite elementsexpressions

`X=inv(A)*B*C`

and`X=A.i()*B*C`

are automatically converted to X=solve(A,B*C)Corrected conversion to

`unsigned int`

vectors and matricesConfigure script now checks for R version 3.0.3 or newer to enable complex divide-and-conquer SVD in case of R-supplied LAPACK
