[Rcpp-devel] Rcpp shortcut for R's as.matrix and as.vector

2010-03-29 Thread Douglas Bates
Most Lapack routines for solving linear systems from factorizations allow the right hand side to be a matrix, thereby providing for solving multiple systems in one call. I would like to preserve this capability while also allowing for the most common case where the rhs is a vector. Also, I would
