Linear algebra utility functions, generally performed on matrices or vectors.
static void StoreSettings(const std::string &name)
Take all parameters and function mappings and store them, under the given name.
The core includes that mlpack expects; standard C++ includes and Armadillo.
static void Add(util::ParamData &&d)
Adds a parameter to the hierarchy; use the PARAM_*() macros instead of this (i.e. ...
bool didParse
True, if IO was used to parse command line options.
Definition: io.hpp:308
static void RestoreSettings(const std::string &name, const bool fatal=true)
Restore all of the parameters and function mappings of the given name, if they exist.
This structure holds all of the information about a single parameter, including its value (which is s...
Definition: param_data.hpp:52
static void MakeInPlaceCopy(const std::string &outputParamName, const std::string &inputParamName)
Given two (matrix) parameters, ensure that the first is an in-place copy of the second.
Parses the command line for parameters and holds user-specified parameters.
Definition: io.hpp:172
static T & GetRawParam(const std::string &identifier)
Get the raw value of the parameter before any processing that GetParam() might normally do...
static IO & GetSingleton()
Retrieve the singleton.
The timer class provides a way for mlpack methods to be timed.
Definition: timers.hpp:45
static std::map< char, std::string > & Aliases()
Return a modifiable list of aliases that IO knows about.
static void SetPassed(const std::string &name)
Mark a particular parameter as passed.
std::map< std::string, std::map< std::string, void(*)(util::ParamData &, const void *, void *)> > FunctionMapType
Map for functions and types.
Definition: io.hpp:298
static T & GetParam(const std::string &identifier)
Get the value of type T found while parsing.
static void ClearSettings()
Clear all of the settings, removing all parameters and function mappings.
static bool HasParam(const std::string &identifier)
See if the specified flag was found while parsing.
util::BindingDetails doc
Holds the bindingDetails objects.

Definition: io.hpp:299
static std::string GetPrintableParam(const std::string &identifier)
Cast the given parameter of the given type to a short, printable std::string, for use in status messa...
This structure holds all of the information about bindings documentation.
static std::map< std::string, util::ParamData > & Parameters()
Return a modifiable list of parameters that IO knows about.
std::string programName
Holds the name of the program for –version.
Definition: io.hpp:312
static std::string ProgramName()
Get the program name as set by the BINDING_NAME() macro.
