C++ Libraries in GetIt: Eigen

An ongoing project we have is to ensure more popular, well-known C++ libraries are updated to work with C++Builder, and available to you from within GetIt, our package manager. You may have seen a post earlier this year about real-world (non-demo) apps that you can use with C++Builder and CMake, for example, and this is related.

Today, let’s look at Eigen.

Eigen is a very famous C++ library for linear algebra. Or, to quote, “Eigen is a C++ template library for linear algebra: matrices, vectors, numerical solvers, and related algorithms.” 

If you do any kind of moderately complex math in C++, most likely you’ve come across Eigen, and it regularly pops up as a recommended library.

Eigen is available in GetIt.

When you use RAD Studio, you can mix C++ and Delphi code together. I have a blog postvideo, and example source code for doing so, in both directions – adding Delphi to C++, and adding C++ to Delphi! If you want to make use of C++ libraries from within Delphi, check those out, and look into making use of RAD Studio.
