I’ve worked on this for a couple weeks and can’t make a reproducible example outside my codebase. That’s why I need help! I’m not sure if this is a problem with pybind11 or Armadillo. It’s not a problem with Carma since it happens in situations with no conversion going on. I’ve been trying to boil ..

Using the armadillo library, one may write // Log if this is non-finite if ( ! averages.is_finite() ) { arma::uvec nonfinites = arma::find_nonfinite( averages ); PI_LOG_WARN( "There are ", nonfinites.n_elem, " of ", averages.n_elem, " non-finite elements in the band border averages of the input signal." ); } I’d like to simplify this without using ..

I want to compute the cross product (ZZ‘) of a matrix Z with dimensions n x p (n is the number of rows and p is the number of columns). For some analyses I have to compute this cross product repeatedly and I was looking for an efficient way to do it. I know that ..

I am trying to import a matrix generated in MATLAB into armadillo. For example, I have a matrix "A" which is 100×1 double. I used information from a previous question on stackoverflow to generate a binary file using MATLAB: % Generate LocalX.bin name = ‘LocalX.bin’; [F,err] = fopen(name,’w’); if F<0,error(err);end fwrite(F,LocalX, ‘int32’); fclose(F); and I ..

I came across an error after upgrading ubuntu. I was resisting upgrading it to avoid library mismatch for older projects. I was using 16.04, and I upgraded to 18.04. Also, the ROS versions changed from kinetic to melodic. The problem appeared compiling a ROS project that uses armadillo. It was working ok, but now I ..

I want to use the armadillo library in my C++ code. I downloaded it, and copied both the "include" and "lib_win64" folders into a new folder in my solution folder called "Dependencies". The include folder contained another folder within which contained all the header files. The lib_win64 folder contained "libopenblas.dll" and "libopenblas.lib". Now, I opened ..

I am looking to use armadillo in Clion. I used homebrew to install on my mac, but am having difficulty including the library in my executable, when using #include <armadillo>. I am getting "armadillo file not found." How can I mitigate this issue? I am new to the external library game in C++, as I’ve ..

Initially, I was importing some data from R directly into a C++ function like so: #include <RcppArmadillo.h> using namespace Rcpp; // [[Rcpp::depends(RcppArmadillo)]] List gibbs(List dat) { int N = dat["N"]; arma::vec y = dat["y"]; … } Eventually, I needed more than just N and y (the input_data list has many separate vectors and matrices I ..

since last week I’m working with the "Armadillo" C++-library. I started with a default 64-bit C++ application in Microsoft Visual Studio. For the installation I followed the steps in the post below: How can I install Armadillo on Windows? Following these steps, everything worked fine for me. But now I have to expand my C++-application ..

I’m using the pinv function from the armadillo library to find the pseudo inverse in C++. It works, but the memory usage is quite high (>10GB), and I’m only running it on a small portion of my data. This method won’t scale up. Is there a less memory intensive way to calculate the pseudo inverse? ..
