Dear all, I'm porting some R code to C++ using the armadillo framework (I'm using operations on complex matrices, etc.). The final goal is of course to wrap the code using RcppArmadillo. Currently, I'm still struggling with my little C++ knowledge. Does anyone know of an Armadillo mailing list where I could ask C++ questions?
Just in case, I'll ask here too. I have a small 3x3 matrix that I generate in a nested for loop, and I want to insert this matrix as a block inside a larger matrix. In R language, I'd want to use a construct like, A[ seq(ii, ii+2), seq(jj, jj+2)] <- matrix(rnorm(9), 3, 3) I tried the following as a test, mat A = "0 0 0; 0 0 0; 0 0 0;"; A.submat(1,1,1,1) = 1; but it seems that .submat is only to view elements, not assign them (the `[<-` method in R). Any tip? Sincerely, baptiste _______________________________________________ Rcpp-devel mailing list [email protected] https://lists.r-forge.r-project.org/cgi-bin/mailman/listinfo/rcpp-devel
