15.4 Source-code of GOA in C++

Listing 15.3 provides the C++ implementation of GOA technique. For the

linear algebra the Armadillo library was used [1]. It saves the user from the

additional time overhead needed to implement vectorized operations. It allows

us also to use automatic multi-threading.
