Dear all, Consider solving Ax=b. According to the Armadillo docs it is so that if we know that A is upper triangular then declaring this should lead to a faster solution, i.e. (my understanding) solve( trimatu(A), b )
should be faster than solve( A, b ) My limited experience is that this is not the case (I have tried where A is 14x14). I have read (SO) that Armadillo does not have "proper" forward/backward substitution implemented, so I am not sure what declaring trimatu(A) should do when solving linear equations. Does anyone have any insight on these issues? Thanks in advance Søren _______________________________________________ Rcpp-devel mailing list Rcpp-devel@lists.r-forge.r-project.org https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
