boost::any value
The actual value that is held.
Definition: param_data.hpp:82
Linear algebra utility functions, generally performed on matrices or vectors.
Definition: add_to_po.hpp:21
bool wasPassed
True if the option was passed to the program.
Definition: param_data.hpp:66
The core includes that mlpack expects; standard C++ includes and Armadillo.

This overload is called when nothing special needs to happen to the name of the parameter.
